Before kernel validates that fd is valid, it checks itimerspec struct
with timespec_valid(). This struct is currently not initialised in test,
which can cause failures, for example:
timerfd_settime01 1 TFAIL : timerfd_settime01.c:121: timerfd_settime()
failed unexpectedly; expected: 9 - Bad file
descriptor: TEST_ERRNO=EINVAL(22): Invalid argument
timerfd_settime01 2 TFAIL : timerfd_settime01.c:121: timerfd_settime()
failed unexpectedly; expected: 14 - Bad address:
TEST_ERRNO=EINVAL(22): Invalid argument
Fix this by giving fields in this struct some deterministic values
(zero in this patch).
