[evolution] Flatpak: Hide Save All button in attachment bar

[Milan Crha <mcrha src gnome org>]

    Flatpak: Hide Save All button in attachment bar
    
    The GtkFileChooserNativePortal does not support GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER
    at the moment, which 'Save All' button uses, thus hide the button when running
    under Flatpak for now.
