Aaron Conole ee00af6017 test: remove strict timing requirements some tests
The tests 'alarm_autotest' and 'cycles_autotest' rely on the underlying
system having very accurate and precise timing.  On systems where the
timing isn't as rigid, or the load is particularly high, these tests are
unreliable since the wake latency from the scheduler can be high enough
to miss the timing window.

Remove the timing related tests from the test suites.  These tests now
ensure the add/remove callback infrastructure unit tests, but drop the
waits and reliance on system timing and load.

This avoids FAIL on various testing infrastructures.
