To exclude a possible race conditions, I re-built lightdm-gtk-greeter
changing the order above, but the problem remains the same with only
the suspend and the shutdown buttons showing.

Then I had a look
at /usr/share/polkit-1/actions/org.freedesktop.login1.policy

reboot and shutdown (respectively suspend and hibernate) permissions
differ inside the "multiple-sessions" stanza.
It is allow_active "yes" for shutdown (respectively suspend) whereas
allow_active "auth_admin_keep" for reboot (respectively hibernate).

Forcing allow_active to "yes" for reboot and hibernate in the
multiple-sessions stanza allows to get all 4 buttons.

But I cannot explain the multiple-session thing, normally
there is only one session (lightdm) if no one else is logged in.
