RPM build error "This macro requires some arguments" occurs on Fedora 31

[syuu1228]

It seems like rpm macro %systemd_postun requires one argument starting from Fedora 31, otherwise it causes the error.
The solution is passing systemd unit name just like %systemd_post and %systemd_preun.

I also just faced it on https://jenkins.scylladb.com/job/scylla-master/job/debug-jobs/job/centos-rpm-debug/53/consoleFull Ran on muninn using dbuild. If I run with no dbuild, I'm OK.

@syuu1228 I tried to build centos-rpm using dbuild, and get syntax error:
