overlay: disable systemd-resolved DNS stub listener

CoreDNS doesn't play nice with default systemd-resolved configuration - see coredns/coredns@master/plugin/loop/README.md#troubleshooting-loops-in-kubernetes-clusters. OKD should boot with systemd-resolved enabled, but without DNS stub listener (127.0.0.53) so that external DNS would be used Fixes okd-project/okd#380
