[PATCH BlueZ 6/6] test-bap: Add Broadcast Source Release test

[Iulia Tanasescu <iulia.tanasescu@xxxxxxx>]

BAP/BSRC/SCC/BV-37-C [Releases Broadcast] (page 176):

    Test Purpose:
    Verify that a Broadcast Source IUT can release a broadcast
    Audio Stream and transition from Configured state to Idle
    state.

    Pass verdict:
    The IUT stops transmitting periodic advertising.
