Russ Magee f5be3578a8 1/3 Updated Makefile to allow VENDOR flag (adds -vendor to version string)
2/3 Added vendor/ dir to lock down dependent pkg versions.
The author of git.schwanenlied.me/yawning/{chacha20,newhope,kyber}.git has copied
their repos to gitlab.com/yawning/ but some imports of chacha20 from newhope still
inconsistently refer to git.schwanenlied.me/, breaking build.
Licenses for chacha20 also changed from CC0 to AGPL, which may or may not be an
issue. Until the two aforementioned issues are resolved, locking to last-good
versions is probably the best way forward for now.

To build with vendored deps, use make VENDOR=1 clean all

3/3 Moved body of CI push script into bacillus/
