[eog] Set sensitivity for Save and Undo on image load

[Felix Riemann <friemann src gnome org>]

commit 011d68548f93cfe2fcf20c51075d4d5f71389472

    Set sensitivity for Save and Undo on image load
    
    They were disabled before which made it impossible to do changes to an
    image, switch to another, switch back and try to save/undo the changes.
    Respect lockdown settings for Save.
