If an app registers a network agent and doesn't have NETWORK_FACTORY or
PERMISSION_MAINLINE_NETWORK_STACK, but does have
CREATE_APP_SPECIFIC_NETWORK, ConnectivityService will:
- Allow it to create a network
- Force the capabilities to contain only the app's UID
- Force the network to be restricted
- Ignore attempts to change the UID or make the network non-restricted
