This test will require /dev/rtc0, the default RTC device, or one
specified by user to run. Since this default RTC is not guaranteed to
exist on all of the devices, so check its existence first, otherwise
skip this test with the kselftest skip code 4.

Without this patch this test will fail like this on a s390x zVM:
# selftests: timers: rtcpie
# /dev/rtc0: No such file or directory
not ok 1 selftests: timers: rtcpie # exit=22

With this patch:
# selftests: timers: rtcpie
# Default RTC /dev/rtc0 does not exist. Test Skipped!
not ok 9 selftests: timers: rtcpie # SKIP
