audiofuntest: Add --active-mic-channels

CL:425596 supports testing only a subset of mic channels.
For audiofuntest, we also need this feature to ignore invalid channls,
otherwise audiofuntest will wait all invalid channels until timeout,
impacting the performance of audio_loop test.

BUG=b:35941747
TEST=Run audio_loop test
