Actually reload user managers and backport unit reload macros

The macro expansions would only work when compiled with a recent version of
systemd. We don't want to create a dependency loop like this, let's just expand
the string manually.

Also backport the patch adding %systemd_postun_with_reload and
%systemd_user_postun_with_reload so a FPC documentation change can be filed.

Subject: [PATCH] rpm: add %systemd_postun_with_reload and
%systemd_user_postun_with_reload
For some units, the package would like to issue a reload. The machinery was
already in place since c9615f73521986b3607b852c139036d58973043c:
systemctl reload-or-restart --marked
Enqueues restart jobs for all units that have the 'needs-restart'
mark, and reload jobs for units that have the 'needs-reload' mark.
When a unit marked for reload does not support reload, restart will
be queued.
The new macros allow a reload to be issued instead of a restart.
Based on the discussion on fedora-devel:
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/IJSUGIEJNYZZRE53FF4YFUEBRHRAVIXR/
Tested using dummy package https://github.com/keszybz/rpm-test-reload.
