Add Google's audio libs to replace CM's ones.

On CM11 M8, in some cases you can't set audio volume in a few apps^1,
and logcat shows this error:
E/audio_hw_primary(  215): out_set_volume: Could not get ctl for mixer cmd - Compress Playback 9 Volume

Using Google's audio libs, I solved this problem.
