utils: bdaddr: Add service to set Bluetooth device (MAC) address
The Bluetooth chip does not come with a unique Bluetooth device (MAC)
address configured out of the box. This means that we manually need
to configure the device address.
Otherwise BT will stop working from v6.5 kernel version onwards.

message, built an rc and shell script around this service,
and added SELinux policies.]
