[LTP] [PATCH v2] clock_settime03: change to use CLOCK_REALTIME

[Li Wang <liwang@redhat.com>]

CLOCK_REALTIME_ALARM requires an RTC with alarm support, which may not be
present on a system. In that case, the kernel will return EOPNOTSUPP, which
is defined as ENOTSUP in userspace.

Here use CLOCK_REALTIME instead of the CLOCK_REALTIME_ALARM because we do
NOT need suspend the SUT during test.
