description:
sysinst: Enable mDNS lookups via NSS when enabling mdnsd.

Add/remove "multicast_dns" to the hosts: line in /etc/nsswitch.conf when
toggling the mdnsd rcvar. Change the label from "Enable mdnsd" to "Enable
multicast DNS support" to better describe what's going on here.

Now when you enable multicast DNS support in the installer, the host will
both advertise itself on the network and resolve .local network names.
