Since commit 6610e0893b8bc ("RTC: Rework RTC code to use timerqueue for
events"), PIE are completely handled using hrtimers, without actually using
any underlying hardware RTC.
Move PIE testing out of rtctest. It still depends on the presence of an RTC
(to access the device file) but doesn't depend on it actually working.

Rework rtctest to use the test harness to better handle skipping tests
(e.g. when alarms are not available). Also, it now handles timeout so it
will not block expecting an alarm that never comes.
