Systems that have an accurate real-time clock may have an initial unsynchronized time that is close enough to the synchronized time that the final adjustment doesn't trigger a waking "clock set" event. Have timesyncd touch a file in its runtime directory as a secondary signal for synchronization. Continue to support the timerfd-based trigger as a sufficient condition when the watchfile is not present. Closes issue #8683
