convert to using pidfile...  This prevents multiple wpa_supplicants
running at the same time causing problems w/ wifi not working..

the patch will be submitted upstream...  The next step if someone wants
to push it upstream is to break os_unix.c up so that all these other
utilities don't need libutil..
