[OE-core] [PATCH 1/1] lib/oe/patch.py: Fix applying a directory as a patch

[Tomasz Dziendzielski]

If a SRC_URI content ends with '.patch' bitbake is
trying to apply it as it's a patch file.

It causes that if we use git repository for 'patch' package
the bare clone is extracted to a directory
(i.e. build/downloads/git2/git.mirror.org.patch/) which is considered
to be a patch file, so patch.py tries to apply that directory as a patch
which ends up with a failure.
