[efi] add mbr UEFI marker for partition scheme reselection
* without the marker, an UFD created as MBR for UEFI will be seen as MBR for BIOS + UEFI. We want Rufus to be able to select the settings that were used for the drive creation. * Also hides #116 under the carpet and fix non RUFUS_DEBUG compilation
