[reproducer] Add virthost DNS record

openshift-metal3/dev-scripts writes an entry for virthost in
/etc/hosts, but the dnsmasq server created by libvirt-manager
does not read /etc/hosts.

Add virthost.<cluster>.<domain> to the utility DNS host record to
support devscripts local registry mirror when mirror_images is enabled.
