kernel-rt: use correct branch names and new git SRC_REV format

The RT kernel recipe was not updated to reflect the new git SRC_REV format nor
to take advantage of the recent updates made to the underlying infrastructure.
These fixes bring it up to date with the other linux-yocto* recipes and fix
various build issues people were seeing.
