Adapt Readme and script to monero gitian build signing

Browse source 
The sigs should be produced in a seperate step by default.
Remove windows and osx sig options that are not needed for monero.

instructions. Please also consult their documentation, when running into problems.
The signing is left as inherited from bitcoin at the moment, since building currently
still fails with libiconv.

Manual and Building
-------------------
The instructions below use the automated script [gitian-build.py](https://github.com/betcoin/bitcoin/blob/master/contrib/gitian-build.py) which only works in Ubuntu. For manual steps and instructions for fully offline signing, see [this guide](./gitian-building/gitian-building-manual.md).
MacOS code signing
------------------
In order to sign builds for MacOS, you need to download the free SDK and extract a file. The steps are described [here](./gitian-building/gitian-building-mac-os-sdk.md). Alternatively, you can skip the OSX build by adding `--os=lw` below.
The instructions below use the automated script [gitian-build.py](https://github.com/betcoin/bitcoin/blob/master/contrib/gitian-build.py) which only works in Ubuntu.
It calls all available descriptors. Help for the build steps taken can be accessed with `./gitian-build.py --help`.

In order to sign gitian builds on your host machine, which has your PGP key, fork the gitian.sigs repository and clone it on your host machine:
While gitian and this build script does provide a way for you to sign the build directly, it is recommended to sign in a seperate step.
This script is only there for convenience. Seperate steps for building can still be taken.
In order to sign gitian builds on your host machine, which has your PGP key,
fork the gitian.sigs repository and clone it on your host machine,
or pass the signed assert file back to your build machine.
```
git clone git@github.com:bitcoin-core/gitian.sigs.git
git remote add satoshi git@github.com:satoshi/gitian.sigs.git
git clone git@github.com:monero-project/gitian.sigs.git
git remote add fluffypony git@github.com:fluffypony/gitian.sigs.git
```
Build Binaries
-----------------------------
Windows and OSX have code signed binaries, but those won't be available until a few developers have gitian signed the non-codesigned binaries.
To build the most recent tag:
`./gitian-build.py --detach-sign --no-commit -b fluffypony 0.0.20`
`./gitian-build.py --detach-sign --no-commit -b fluffypony 0.14.0`
To speed up the build, use `-j 5 -m 5000` as the first arguments, where `5` is the number of CPU's you allocated to the VM plus one, and 5000 is a little bit less than then the MB's of RAM you allocated. If there is memory corruption on your machine, try to tweak these values.
If all went well, this produces a number of (uncommited) `.assert` files in the gitian.sigs repository.
You need to copy these uncommited changes to your host machine, where you can sign them:
If you do detached, offline signing, you need to copy these uncommited changes to your host machine, where you can sign them. For example:
```
export NAME=satoshi
gpg --output $VERSION-linux/$NAME/bitcoin-linux-0.16-build.assert.sig --detach-sign 0.16.0rc1-linux/$NAME/bitcoin-linux-0.16-build.assert
gpg --output $VERSION-osx-unsigned/$NAME/bitcoin-osx-0.16-build.assert.sig --detach-sign 0.16.0rc1-osx-unsigned/$NAME/bitcoin-osx-0.16-build.assert
gpg --output $VERSION-win-unsigned/$NAME/bitcoin-win-0.16-build.assert.sig --detach-sign 0.16.0rc1-win-unsigned/$NAME/bitcoin-win-0.16-build.assert
export NAME=fluffypony
export VERSION=0.14
gpg --output $VERSION-linux/$NAME/monero-linux-$VERSION-build.assert.sig --detach-sign $VERSION-linux/$NAME/monero-linux-$VERSION-build.assert
gpg --output $VERSION-osx-unsigned/$NAME/monero-osx-$VERSION-build.assert.sig --detach-sign $VERSION-osx-unsigned/$NAME/monero-osx-$VERSION-build.assert

Make a pull request (both the `.assert` and `.assert.sig` files) to the

You can also mail the files to Wladimir (laanwj@gmail.com) and he will commit them.
```bash
gpg --detach-sign ${VERSION}-linux/${SIGNER}/bitcoin-linux-*-build.assert
gpg --detach-sign ${VERSION}-win-unsigned/${SIGNER}/bitcoin-win-*-build.assert
gpg --detach-sign ${VERSION}-osx-unsigned/${SIGNER}/bitcoin-osx-*-build.assert
gpg --detach-sign ${VERSION}-linux/${SIGNER}/monero-linux-*-build.assert
gpg --detach-sign ${VERSION}-win-unsigned/${SIGNER}/monero-win-*-build.assert
gpg --detach-sign ${VERSION}-osx-unsigned/${SIGNER}/monero-osx-*-build.assert
```
You may have other .assert files as well (e.g. `signed` ones), in which case you should sign them too. You can see all of them by doing `ls ${VERSION}-*/${SIGNER}`.
This will create the `.sig` files that can be committed together with the `.assert` files to assert your
Gitian build.
`./gitian-build.py --detach-sign -s satoshi 0.16.0rc1 --nocommit`
