user-status: Honor lockdown settings

Browse Source 
Right now, the user status menu always contains actions to logout
and lock the screen, and the user switching action only depends on
the technical availability of the functionality.
All those items should honor the lockdown settings defined in
org.gnome.desktop.lockdown.
