Subject: Do not accidentally build this spec for F < 30


After https://fedoraproject.org/wiki/Changes/RemoveObsoleteScriptlets
this spec file lacks the install-info scriptlets required for older
distributions than Fedora 30.

This makes sure the build fails if you ever tried to build this
scriptlet-less F30-and-later spec file for older distributions such
as F28 or EL7 or ...

A failed build is better than silently not properly installing the
rpm package.
