[gnome-shell] Pass events to the OSK in dialogs which grab events

[Marge Bot <marge-bot src gnome org>]

commit 66331e124410a9fff1f5fd173e0b771990662bd5

    Pass events to the OSK in dialogs which grab events
    
    With commit c29e0cf6e60a1296b43fc33d94f2acc649046cf9 the grabHelper
    already started using a similar mechanism to funnel events to the osk
    while a ClutterGrab is in effect. ModalDialog, the unlockDialog and
    lookingGlass don't make use of the grabHelper though, they use
    Main.pushModal() themselves, so those need to funnel the events to the
    OSK themselves.
