This is because when you log out, you create a new lightdm-gtk-greeter
process and you see the change. However, inside one given
lightdm-gtk-greteer process, the power_menu remains static.
When libpam-systemd is removed, lightdm does not have anymore its own
logind session. If no one else is logged, there is no more multi-session
and the full power_menu can show up.
If both libpam-systemd and systemd are removed I guess the
lightdm_get_can_* () tests switch to consolekit and upower.

I tried but as systemd is PID1, I  just removed libpam-systemd
and restarted systemd-login.service. I had to login with lightdm and
logout to see the change (by running a new lightdm-gtk-greeter
process).

I do not know how to achieve this. The best I could do to remove the
gtk_widget_hide calls. The 4 items in the menu show up and the action
fails when permission is not granted. But it is not user friendly
since no feedback is given.
Moreover, there is still this inconsistent behavior between shutdown
and reboot (respectively suspend and hibernate) in case of
multiple-sessions.
