[evince] [shell] Remove DBUS conditionals from TotemScrsaver

[Carlos Garcia Campos <carlosgc src gnome org>]

    [shell] Remove DBUS conditionals from TotemScrsaver
    
    Now that GDBus is in GIO, there's no need to conditionally compile this
    code. Just allow passing %NULL for @connection in totem_scrsaver_new()
    to disable using DBUS to inhibit the screensaver.
