This adds a bit heuristic to the docker entrypoint in order to move our
API towards "docker run [...] kasproject/kas build kas.yml" - without
breaking existing users. And now you can also do
docker run --rm kasproject/kas --version

Your docker host setup uses broken aufs as storage driver. Adjust the docker

configuration to use a different driver (overlay, overlay2, devicemapper). You

may also need to update the host distribution (e.g. Debian Jessie -> Stretch).
