Use registerSystemDefaultNetworkCallback to listen underlying network

This commit replaces requestNetwork with
registerSystemDefaultNetworkCallback to listen the underlying
network.

Previously, Vpn needs to create a request for default network.
Now, ConnectivityManager provides a new API which can listen the
underlying network. So use the new API -
registerSystemDefaultNetworkCallback instead.
