    testsuite: Fix a comparison which depended on GLib hash table ordering
    
    In GLib 2.59, the iteration order of GHashTable was changed (its order
    has always be, and will always be, undefined). This has broken some
    comparisons in check_language() in test-language.c, which assumed a
    certain hash table ordering for the results returned by
    gtk_source_language_get_*().
    
    Fix that by using an unordered comparison function. This should be
    backwards compatible with older GLib versions.
