api-impl-jni/audio/android_media_AudioTrack.c: make this stuff noop by default

Browse Source 
this particular implementation never worked particularly great, and thanks
to hardcoding could cause more harm then good.

export `HAX_AUDIOTRACK_PCM_DEVICE=sysdefault:CARD=Generic_1` to restore
previous behavior

TODO: use libOpenSLES to implement this maybe? we have to have it anyway...
