Enhance the logic behind the 'auto' mode a bit by only updating the
SRCREV if the changes are already found upstream. The logic is simple:
update SRCREV only if the current local HEAD commit is found in the
remote branch (i.e. 'origin/<branch_name>'). Otherwise resort to
patching.
This affects a couple of the oe-selftest tests so update those as well.
