Fix post-uninstall cleanup of /var/lib/nfs

b63be16 ("Rely on presets and use standard macros for systemd unit
handling (bz 2218006)") moved the logic to clean up /var/lib/nfs into
the %posttrans scriptlet.  The problem is that the %posttrans scriptlet
runs during install and upgrade, not during uninstall.  That creates a
scenario where uninstalling nfs-utils leaves the nfs-server.cleanup
file behind in /var/lib/rpm-state.  When a subsequent install of
nfs-utils encounters this file, it will delete /var/lib/nfs/statd
and /var/lib/nfs/v4recovery:

--8<--
$ rpm --verify nfs-utils-1:2.7.1-2.el10.x86_64
missing     /var/lib/nfs/statd
missing     /var/lib/nfs/statd/sm
missing     /var/lib/nfs/statd/sm.bak
missing     /var/lib/nfs/v4recovery
--8<--
