Change our AVRCP capabilities if the remote device only supports 1.3 

This prevents issues with devices that only support 1.3 but can not
handle forward compatability like some Alpine Carkits.

Bug: 37943083
Test: Connect to Alpine carkit that only supports 1.3 and see new features
      are used.
