cyclictest: Ensure that next wakeup time is never in the past

The calculated next wakeup time is already in the past, if the latency
is longer than the interval. Thereby latency is detected that does not
correspond to latency caused by the system but by cyclictest itself.

Force forward the next wakeup time past now.
