[autotest] audio_AlsaAPI: use hw:X,Y to access playback devices

The ALSA API behavior when accessing device using sysdefault is different
from the behavior when accessing device using hw:X,Y directly.
Use hw:X,Y to access and test all playback devices on the board instead
of testing only sysdefault device.

BUG=chromium:617516
TEST=run audio_AlsAPI test on auron_paine.
