systemd/polkit: add comment about why systemd preset isn't used (MR 5377)

ci:skip-vercheck for *all* packages in the branch just to so that this

+# Not running 'systemctl preset' on polkit

+#  # The implied (systemctl preset) will fail and complain, but the macro hides
+#  # and ignores the fact.  This is in fact what we want, polkit.service does not
+#  # have an [Install] section and it is always started on demand.
