- Bump to version 11

- Don't pass -f to rm in %service_add_post nor %systemd_user_post

- Add a %systemd_user_pre macro that creates a
/run/systemd/rpm/needs-user-preset/$service file for each new
service being installed so %systemd_user_post can call
`systemctl --global preset $service` properly for newly
installed user services (boo#1183051, boo#1183012).

- Fix %systemd_user_post. The --global parameter was handled as if
it was another service name so %systemd_user_post wasn't working
properly. Replace %systemd_user_post with the code from
%service_add_post it was being expanded to but correctly passing
--global to systemctl (boo#1183051, boo#1182661).
