Daniel Norman fb4aadf622 Replaces 'oneshot' and 'interface' with 'onrestart restart audioserver'. 
This default service should still restart on audioserver restart because
audioserver uses 'onrestart restart vendor.audio-hal-2-0' for restarts.

Bug: 138114550
Bug: 80227481
Test: for i in {0..100}; do \
      adb shell 'ps|grep audio;killall audioserver;ps|grep audio' \
      && sleep 2; \
      done
Test: Ran steps mentioned in http://b/80227481#comment1, device did not
get stuck in boot animation. Killing either audioserver or audio-hal
caused both to restart (just once) and the device booted correctly after
the sleep finished.
