templates: lxc-system-manage: Send correct DNS over dhcp

Browse Source 
We should set the correct DNS IP address via DHCP so containers can get
a valid entry. This fixes a problem where the DNS inherits the DNS
server from the host and the host uses the localhost IP in case it's
running a local DNS caching resolver such as dnsmasq.
