[PATCH BlueZ] audio/transport: Emit Volume changed if endpoint is source

Change set_volume to send a Volume PropertyChanged signal also if
transport->sink_watch is set (and not only if source_watch is set).

This fixes volume changes signals not being sent for devices like speakers and
headphone adapters with volume control (like Bose Soundlink Revolve or Fiio BTR5).
