Use non-wakeup alarm for delay constraint.

The delay alarm does not need to go off exactly when the time has
passed, so a non-wakeup alarm is suitable for the delay constraint.
A job is expected to go off as soon as its deadline constraint is
satisfied, so we leave the deadline alarm as a wakeup alarm.
