[PATCH 1/6] devtool: extract: remove patches when S=WORKDIR

[Markus Lehtonen <markus.lehtonen@linux.intel.com>]

Before this change, all files from the recipe (SRC_URI), including
patches, were added to to srctree repository when S==WORKDIR. The patch
files are useless as they are automatically applied on top of the
srctree by devtool.

This change causes devtool extract to not commit these unnecessary (and
possibly confusing) patch file(s) into srctree repository.

[YOCTO #7602]
