The firewalld package in Fedora 30 didn't get support for rich rule
priorities, which is required by the libvirt zonefile that's installed
when the build is configured with --with-firewalld-zone, so we need to
set --without-firewalld-zone for that version of Fedora. The needed
feature is already upstream in firewalld, so it just needs another
upstream release to be there. Let's be optimistic and assume that will
happen prior to F31.
