kselftests: timers: Reduce default runtime on inconsistency-check and set-timer-lat

For the default run_timers target, the timers tests takes the
majority of kselftests runtime.

So this patch reduces the default runtime for inconsistentcy-check
and set-timer-lat, which reduced the runtime almost in half.
