tests: drivers: counter: Test failure when counter is running upwards

The "test_late_alarm_error" test vector comes with an update that
should result in test failure when the target counter runs upwards.
That test vector attempts to set an alarm event that is passed the
current tick value. Therefore, counter's direction should be exercised
and then an appropriate alarm event should be defined.
