rootless: require subids to be present
Most images won't work without multiple ids/gids. Error out
immediately if there are no multiple ids available.
The error code when the user is not present in /etc/sub{g,u}id looks
like:
$ bin/podman run --rm -ti alpine echo hello
ERRO[0000] No subuid ranges found for user "gscrivano"
