Subject: base.bbclass: If unpacking again, wipe out ${S}/patches

If we unpack again, its assumed the data in any patches directory is invalid
since do_patch will run again. This ensures old patch data doesn't get
reused in a confused way.

Ideally we should probably wipe out ${S} here but that is probably a change
for another time.
