lib/oe/patch: fix for git am not cleaning up after itself
Unfortunately it appears that under certain circumstances, a failed
git am followed by git am --abort won't clean up any changes the patch
might have made - this was seen when running "devtool extract" on the
unzip recipe; unzip-6.0_overflow3.diff has a malformed date as far as
git am is concerned but it triggers this condition. Add a
git reset --hard HEAD followed by git clean -f in order to recover from
this scenario.
