    file: Avoid blurry missing-image in broken links
    
    When links are broken, i.e., their target is not found, the available
    icon names for this type of file are inode-symlink or inode-x-generic.
    
    None of them exist in adwaita-icon-theme, so, GTK adds a blurry
    image-missing icon instead.
    
    As a workaround, use our usual fallback: text-x-generic
    
    Workaround for https://gitlab.gnome.org/GNOME/nautilus/-/issues/2396
