This is part of speeding up cosa build-fast; here the dhclient
run takes about a second out of 11 (after other speedups) so
that's a 9% win. After rebasing on
#1289
I'll also drop out the virtio-net NIC entirely which will help
us ensure tasks that shouldn't pull external content don't.

This has notably caused any cosa build that takes the VM path that previously did not run cosa fetch to fail. For example:

https://github.com/coreos/coreos-ci-lib/blob/9319569ddedff8e9d1819a87815cc349ff642380/vars/fcosBuild.groovy#L31

doesn't run a cosa fetch first so I think this is breaking any CI that uses that. Example: https://jenkins-coreos-ci.apps.ci.centos.org/job/github-ci/job/coreos/job/fedora-coreos-config/job/PR-361/1/display/redirect
