prefer to do this in separated cl.

Since I remove this from the base class I need to do it for this subclass as
well. Also- this is not implemented and used yet so its easiest to do now and
let audio use whatever track interface it wants.

 
   void SetLocalAudioSource(webrtc::AudioSourceInterface* source) {
     local_audio_source_ = source;
   }
 
   void SetAudioCapturer(WebRtcAudioCapturer* capturer) {
     DCHECK(!audio_capturer_);
     audio_capturer_ = capturer;
   }
