sculpt: add audio and mixer launcher

Browse Source 
The audio launcher configures the 'bsd_audio_drv' component for normal
use where the micrphone selection should work on most Thinkpads.

The mixer launcher configures the 'record_play_mixer' component for
use with the 'audio' launcher and provides also examplary rules for
vbox6 launchers.
