In the mutex and semaphore tests, main thread will sleep for 10 ticks
to wait for test thread to finish its work. And test thread will wait
5 ticks for timeout test. This means that test thread has 5 ticks to
finish its job.
On platform where idle thread has low power mode enabled
(e.g. it8xxx2_evb), latency in waking up from low power mode will cause
main thread to wake up early before test thread has finished its work.
This symptom will break next test (osThreadGetCount() not equal to 2).
This change makes the test threads have a full 10 ticks to finish its job.
