The following replaces unlabeled_t with network_t for
better characterization of the flow out/in checks in
SELinux, as well as to allow for mls packets to
flow out/in from the network since network_t would allow
the full range of MLS labels, as opposed to the unlabeled init sid
that only allows system-hi.
