kpatch-build: make clean_cache() wipe out ~/.kpatch completely

Browse Source 
When wiping out the ~/.kpatch cache before replacing it with a new
kernel source, there's no need to keep anything around.  Just wipe it
all out and start over.

Also, when building with the -s option, it doesn't need to touch
~/.kpatch/version or ~/.kpatch/src, so it can just skip the cleaning.
That keeps the previous cache around for the next incantation of
kpatch-build without '-s'.
