statd: support gps reference clocks in 'show <hardware|ntp>'

This patch adds a background gps monitor to statd because the gpspipe
program, normally used to interface with gpsd, slows down access to the
operational datastore with *seconds*.

This background monitor is not load bearing for how chrony accesses the
gps + nmea information from gpsd, this is handled separately in SHM.
