bluetooth: backend-native: Handle RegisterProfile failure

Browse source 
Try to register profile support again after RegisterProfile fails, when
BlueZ indicates no one else is implementing the profiles we are
interested in.

Ideally this would rely on a list of UUIDs supported by the profile
manager instead of the adapter, but BlueZ has no such API.
