[PATCH BlueZ 0/1] Add cover art support

BlueZ wasn't able to display cover art in car's headunits due to missing
cover art support. Add missing pieces to allow sending cover arts:

 - Add AVRCP BIP Cover Art Responder
 - Advertise Cover Art Support
 - Update bluetooth service to have at least read only access to home directories (where cover images are located)

Tested on a Fairphone 5 and OnePlus 6T with a VW head unit.
