Fixes bug where puppet fails to run due to domain name

Puppet relies on facter to gather host facts, including domain name.
Unfortunately facter gathers domain name by looking at the first domain
listed in /etc/resolv.conf, rather than the domain name set on the host.
This fix corrects the domain in that file.
