[PRQ#43250] Deletion Request for exiv2-pre

jcjgraf [1] filed a deletion request for exiv2-pre [2]: Upstream exiv2 [1] does no longer publish release candidates, which makes this package redundant. One can use `exiv2-git` to get the latest git version, or `extra/exiv2` to get the latest release, of that package.
