Support podman in make dev-tor

Unfortunately `podman volume` and `docker volume` are not identical,
podman will (sensibly) error if you try to create a volume that already
exists unless you pass `--ignore`, which docker doesn't support and is
only in podman 4.4+.

So we check with `$DOCKER_BIN inspect` first and only create the volume
if necessary.

And apply the same changes to `make clean` as well.
