Handle cron tasks while in crust

mnc goal is to display when will occurs the next cron job.

We drop the "sxmo_screenlock.sh rtc" command and the
SXMO_RTCWAKEINTERVAL variable. We will now only use
"sxmo_screenlock.sh crust" which mean suspend until next cron job
(-2 seconds).

To replicate the old behavior of the blinking phone then returning to
suspension (if needed) we now use a new script.

By example:

*/15 * * * * DISPLAY=:0 sxmo_rtcwake.sh sleep 10

This will trigger a 10s sleep task every 15 minutes (the old default
rtcwake hook).
