profile: Export Remote Audio Volume Control SDP value
Remote Audio Volume Control property in SDP record for HSP HS role
indicates if device supports volume control.
It is required for D-Bus agents which implements audio part of HSP
profile to know if remote device supports volume control or not.
With this change bluez exports status of this SDP property via firt bit
in Features entry in NewConnection() DBus callback method, like for HFP
profile.
