As discussed in
https://pagure.io/releng/failed-composes/issue/6047#comment-899622
the list of 'acceptable' types and formats (in productmd terms)
is locked down in productmd, we cannot just 'declare' new formats
in pungi as we kinda wound up doing by adding these Kiwi
extensions to the EXTENSIONS dict in image_build phase. So
instead, let's return the image_build phase to the way it was,
and add an additional layer of handling in kiwibuild phase for
these awkward cases, which 'translates' the file suffix to a
format productmd knows about already. This is actually how we
would rather behave anyway, because a Kiwi-produced
`vagrant.libvirt.box` file really is the same kind of thing as an
ImageFactory-produced `vagrant-libvirt.box` file; we want them to
have compatible metadata, we don't want them to look like
different things.
