Remove fallback rules in rtl-ordering.html test

Remove fallback rules in rtl-ordering.html test

Issue 545555 describes that unicode-range restricting AAT fonts does not
work properly at the moment. Since Lucida Grande is an AAT font on Mac,
this test case has slight pixel differences on Mac, since Lucida Grande
gets selected to render the "21-" digits in the second line. Let's
remove the explicit fallback declarations, the test should work without
them.

Great, thanks for the review and committing it. Now all blockers should be out
