read monotonic clock with clock_gettime() instead of gettimeofday()
There have been test failures on the osmo-pcu Jenkins builders due
to apparent clock drift. Switch relevant code from gettimeofday()
to clock_gettime() with CLOCK_MONOTONIC to prevent time from going
backwards and causing negative time deltas in calculations.
