Verify that tv_sec value specified in settimeofday() and clock_settime()
(CLOCK_REALTIME case) system calls is non negative.
This commit hides a kernel panic in atrtc_settime() as the clock_ts_to_ct()
does not properly convert negative tv_sec.

ps. in my opinion clock_ts_to_ct() should be rewritten to properly handle
negative tv_sec values.

clock_gettime(2),gettimeofday(2): Remove [EFAULT] error.

Depending on system configuration and parameters, clock_gettime() and
gettimeofday() may not be system calls. If so, passing an invalid pointer
will cause a signal and not an [EFAULT] error.

From a standards perspective, this is OK since passing an invalid pointer is
undefined behaviour.

At the moment it is just an alias for CLOCK_MONOTONIC which reports
the same number.
