    keybindings: Add flag param to grab_accelerator
    
    Add a 'flags' parameters to meta_display_grab_accelerator. This will allow
    e.g. gnome-settings-daemon (through the gnome-shell's GrabAccelerator API) to
    create shorcuts that should descard auto-repeated key events.

    Closes: https://gitlab.gnome.org/GNOME/gnome-settings-daemon/issues/68
