devtool: finish: handle patching when S points to subdir of a git repo

If devtool finish needs to create a patch and have it applied to the
sources for a recipe where S points to a subdirectory of the sources,
then the patch needs to be applied at the root of the repo i.e. we need
to add a patchdir= parameter to the SRC_URI entry.
