[gnome-settings-daemon] xrandr: Prevent possible overflows handling timestamps

[Bastien Nocera <hadess src gnome org>]

    xrandr: Prevent possible overflows handling timestamps
    
    The timestamps are gint64 but we cast them down to guint32, which
    can cause overflows. Avoid that by passing the timestamps as gint64
    all around, even if they are ultimately unused.
