An AudioPlayer playing audio coming from MP2TS data stored in an
 AndroidBufferQueue couldn't be created and realized anymore due
 to:
  - a regression that prevented an OutputMix to be used as the
    sink of an AudioPlayer that had an ABQ as a data source
  - a missing update when the Realize() method became fully
    locked on the object, android_audioPlayer_realize() was
    still trying to lock the already locked AudioPlayer.
Both issues are covered by a CTS test.

Also verify the SLSeekItf is not required when using an ABQ
 source.
