cec-ctl: periodically insert monotonic/wallclock time

The monotonic time and the wallclock time diverge over time. To help
analyze 'pin' logs (--monitor-pin) insert the monotonic and wallclock
time every hour into the pin log, and --analyze-pin will use that
information to keep the wallclock time as reported by -w reasonably
in sync.
