to-wiki.sh: Show the same status for clones.

While it may not be the best way theoretically as theoretically only one
of clones may fail if clones are not perfect, in practice there is more
variance between e.g. different X60 variants than between most of the clones,
yet we put all X60 variants together.
Also in most cases we don't even have a way to tell the clones apart.
