aaudio: stop buzzing when MMAP stream disconnected
When a stream is disconnected, clear the MMAP memory
buffer to prevent the hardware from looping on stale data
and making a buzzing sound.

aaudio: reduce glitching by improving sleep timing
ALways sleep a minimum time to avoid busy wait in real-time thread.
Account for wakeup jitter in threads on the other side of a FIFO.
Avoid race condition that caused a longer sleep than necessary.
Fix calculation of mFreeRunning for capture mode.
Also added systrace logging, which was used to debug this.

Test: Run GStomper on Walleye with MMAP on, see bug
