[libvirt] [PATCH] spec: If installing default network, restart libvirtd

[Cole Robinson]

If libvirt-daemon-config-network is installed while libvirtd is already
running, the daemon doesn't notice the network. Users then have to
manually restart libvirtd (or reboot) to pick up the network.

Instead let's trigger a daemon restart when the package is first installed.
Then the default network is available immediately if libvirtd was already
running.

Plain restart is kind of suboptimal since it will drop all open
libvirt connections. Ideally we would use reload which is meant
for this case, but it's kinda crashy with current git:

And in fact daemon restart is what the spec triggers on libvirt-daemon
upgrade anyways, so this isn't anything new WRT packaging.
