patch: handle if S points to a subdirectory of a git repo

If PATCHTOOL = "git", SRC_URI fetches from a git repo and S points to
a subdirectory of the checked out sources, then we were erroneously
initialising the subdirectory as its own git repo. Check if the returned
top-level repo directory is a subdirectory of WORKDIR and do not
run initialise the source directory if that is the case.

(This was a regression introduced with OE-Core revision
6184b56a7a0fc6f5d19fdfb81e7453667f7da940, however we didn't have a test
that verified the behaviour.)

(From OE-Core rev: 9cca53a2bcbf6809615ce5626c86c6ee481a7a76)
