[OE-core] [CONSOLIDATED PULL 28/36] linux-yocto: allow non-branched repositories to check out

[Saul Wold]

From: Bruce Ashfield <bruce.ashfield at windriver.com>

Not all users of the checkout phase of linux-yocto have all
branches present. This is normal, and should be supported. By
checking for an empty KBRANCH we can avoid validating a branch
that isn't supposed to exist.

[YOCTO #2032]
