Update envvar name for netutils container image

There is a env-var->go-var transform in openstack-operator that matches
env vars to go vars based on _ breaks in the name. Our spec wants
NetUtilsImage which requires NET_UTILS_IMAGE, not NETUTILS_IMAGE to get
the correct camel case. This patch keeps things consistent across the
repos.
