Subject: [PATCH] libidn2: remove dependency on ronn

This is only needed if built from the source repository, since we are
using the release tarball the generated manpage is included. This
removes the "wild" dependency on ruby very deep in the dependency tree.
(util-linux -> systemd -> libidn2 -> ronn -> ruby)
