Infer legacy network type for ConnectivityManager.requestNetwork

ConnectivityManager.requestNetwork pass TYPE_NONE to
sendRequestForNetwork which prevents it from being used with legacy API
requestRouteToHostAddress. This CL infers the legacy network type
automatically from the network capabilities.
