Remove BaseNetworkObserver from Nat464Xlat
Let ConnectivityService talk to Nat464Xlat through NetworkAgnetInfo
directly:
- Nat464Xlat will be created once there is a new network bringing up,
but Netd doesn't expose the method for unregistering unsolicited event.
- ConnectivityService has already registered netd unsolicited event
listener, so Nat464Xlat doesn't need to register unsolicited event
listenser by itself, it can get the unsolicited event from
ConnectivityService directly.
