bluez5: deprioritize audio-gateway if remote is HFP HF + A2DP sink

Browse source 
If remote supports both HFP HF and AG, both may get connected, which
occurs with Pipewire<->Pipewire connection.  In this case, Pipewire on
both sides may pick the audio-gateway profile.

To avoid both sides being audio-gateway, if remote is both A2DP sink and
HF, use lower priority for the audio-gateway profile.  Generally, BlueZ
won't connect both A2DP Source and Sink between same devices at the same
time, so we use that to determine which side should be the receiver.
