Starting with version 18.12.0, Ark has included a custom kerfuffle.xml mime
type to support zstd-compressed files (the mimetype was only added to
shared-mime-info starting with version 1.11, which we don't ship yet). We need
to make sure update-mime-database is run, otherwise Ark will still fail to
recognize those archives.
