Subject: [PATCH 1/3] policy: ignore nameservers when starting lookup thread
 (rh #1031763)

When generating connections, we won't always have DNS information.
Plus, the "best" device already has the default route, which is a
pretty good indication it should be the address we use for looking
up the hostname.
