This reverts commit d365702dbd.
Because buildkit doesn't run an internal resolver, and it bases its
/etc/resolv.conf on the host's ... when buildkit is run in a container
that has 'nameserver 127.0.0.11', its build containers will use Google's
DNS servers as a fallback (unless the build container uses host
networking).
Before, when the 127.0.0.11 resolver was not used for the default network,
the buildkit container would have inherited a site-local nameserver. So,
the build containers it created would also have inherited that DNS
server - and they'd be able to resolve site-local hostnames.
By replacing the site-local nameserver with Google's, we broke access
to local DNS and its hostnames.
