We change the Makefile and dinctl so that instead of having to deploy and then pull a supervisor image, we save it from the local
docker images and load it inside the dind container.
We also fix dind so that it uses the dind hack script from the docker repo as official dind images do (this avoids breaking the
permissions of /dev/pts/ptmx in the host as in https://github.com/kubernetes/kubernetes/issues/18230).
