Don't mark NetworkRequests restricted when they don't have restricted caps
Requests without NET_CAPABILITIES_INTERNET and just the default network
capabilities should not be marked restricted. Without this fix apps
can hit permissions exceptions if they inadvertently make requests
without NET_CAPABILITIES_INTERNET.
