Subject: [PATCH] Assume hb_ft_font_create_referenced if HarfBuzz

* configure.ac (HAVE_HB_FT_FONT_CREATE_REFERENCED):
Remove test, since we now require 0.9.42 and
hb_ft_font_create_referenced has been present since 0.9.38.
* src/ftfont.c (ft_face_destroy, hb_ft_font_create_referenced):
Remove; no longer needed.
