With the transition to modular _libvirt_ daemons, the SELinux policy is
a bit more granular. Unfortunately, the new policy has a funny [bug]: it
assumes directories named `storage` under `/run/libvirt` must be for
_virtstoraged_ and labels them as such, which prevents _virtnetworkd_
from managing a virtual network named `storage`.
To work around this, we need to give `/run/libvirt/network` a special
label so that its children do not match the file transition pattern for
_virtstoraged_ and thus keep their `virtnetworkd_var_run_t` label.
