selftests: timers: Add a test for disarmed SIGEV_NONE timers
timer_gettime() must report a zero it_value for a disarmed timer. For
SIGEV_NONE timers, common_timer_get() reported the remaining time of the
previous arming instead.
Add check_sigev_none_disarm(). It arms a SIGEV_NONE oneshot timer, checks
that a remaining time is reported, disarms the timer and checks that
it_value is zero. Run it for CLOCK_MONOTONIC and CLOCK_PROCESS_CPUTIME_ID,
as CPU timers use a separate implementation.
Without the preceding fix, the CLOCK_MONOTONIC case fails.
