kselftests: timers: Make set-timer-lat fail more gracefully for !CAP_…

…WAKE_ALARM The set-timer-lat test fails when testing CLOCK_BOOTTIME_ALARM or CLOCK_REALTIME_ALARM when the user isn't running as root or with CAP_WAKE_ALARM. So this patch improves the error checking so we report the issue more clearly and continue rather then reporting a failure.
