mdmon: recreate socket/pid file on SIGHUP
Allow mdmon to start while /var/run/mdadm is readonly. Later a SIGHUP
can trigger mdmon to drop its pid and socket once /var/run/mdadm is
writable. Of course one needs the pid to send a HUP, that can be stored
in a distribution specific rw-init directory... For now, rely on a
killall -HUP mdmon to get the files dumped.
