Add Qt6 subpackages

It turns out that version 1.1 supports building a Qt6 version as well
and Fedora already has Qt6 devel packages, so start building also the
Qt6 version for fun and profit.

+Summary: Qt6 wrapper for the minizip library
+%description qt6
+QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package that
+can be used to access ZIP archives. It uses Trolltech's Qt toolkit.
+
+QuaZIP allows you to access files inside ZIP archives using QIODevice API,
+and - yes! - that means that you can also use QTextStream, QDataStream or
+whatever you would like to use on your zipped files.
+
+QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both reading
+from and writing to ZIP archives.
