This update for systemd-rpm-macros fixes the following issues:

- Deprecate '-f'/'-n' options
When used with %service_del_preun, support for these options will be
dropped as DISABLE_STOP_ON_REMOVAL support will be removed on the
next version of SLE (jsc#SLE-8968)
When used with %service_del_postun, they should be replaced with
their counterpart
%service_del_postun_with_restart/%service_del_postun_without_restart
- Introduced %service_del_postun_with_restart()
It's the counterpart of %service_del_postun_without_restart() and
replaces the '-f' option of %service_del_postun().
- Does no longer apply presets when migrating from a disabled initscript (bsc#1178481)
- Fix importing of %{_unitdir}
