The `TEST_RANDOM_GENERATOR` symbol in itself does not imply that a non-random number generator is selected -- that is indicated by the `RNG_GENERATOR_CHOICE` choices, of which only `TIMER_RANDOM_GENERATOR` is a non-random generator. This commit updates the Random subsystem to print the "non-random number generator usage warning" when `TIMER_RANDOM_GENERATOR` is selected, as opposed to when `TEST_RANDOM_GENERATOR` is selected.
