Send LinkProperties update on new capport data

When new CaptivePortalData is received from NetworkMonitor, send a
LinkProperties updated callback.
The updated LinkProperties only contain CaptivePortalData if the
receiver has NETWORK_SETTINGS or MAINLINE_NETWORK_STACK permissions, as
defined in the current callback code.
