devtool: update-recipe: ensure patches get deleted in srcrev mode
Patches that we identify as having been "deleted" (i.e. patches in
SRC_URI that no longer appear in the git tree) need to be dropped even
if we're updating in srcrev mode. This fixes the case where HEAD of the
git tree is valid upstream (i.e. no extra commits), but there are
patches left over in the recipe, e.g. when we do devtool upgrade and
then all of the commits rebased on top of the new branch get skipped.
Fixes [YOCTO #11972].
