Bug Description

 * When running gnome-shell from lightDM, it is not possible to Lock screen or suspend from the user/system Menu.

 * This is due to gnome-screensaver no longer auto-starting when running a non-fallback
   gnome-shell session. We need to explicitly start gnome-screensaver in this case.

 1. From lightDM log into a gnome-shell Session
 2. From user Menu try to Lock or Suspend. It wont work.
 3. using keyboard lock screen with ctrl+alt+L, this forces gnome-screensaver to start.
 4. again try and lock or suspend and it will work.

[Regression Potential]
 None. We are just forcing gnome-screensaver to start for the shell-on-lightdm use case.

== Original Bug Report ==
When running lightDM, the "Lock" option under the gnome-shell User Menu, does not work. Clicking on this does nothing but if you try to lock screen using keyboard (ctrl+alt+L) the it works and also all subsequent clicks on "Lock" option start to work.
