Allow SUW to access registerSystemDefaultNetworkCallback

registerSystemDefaultNetworkCallback is required by WifiTrackerLib to
detect the system default network for UI purposes. Currently this API is
allowed for holders of the NETWORK_SETTINGS permission, but not
NETWORK_SETUP_WIZARD. Since SUW also uses WifiTrackerLib, we should
allow this API for NETWORK_SETUP_WIZARD as well.
