    testsuite: remove box-order test
    
    The test used to test that GtkBox ordered it's children left-to-right in
    CSS, no matter the text direction or pack-type.
    
    But there is neither a pack-type anymore nor does GTK4 do that.
    
    So that test has been broken for yers, it just didn't render anything
    wrong.
