Delete USE_FONT_BACKEND conditional.

(uniscribe_open): Return value changed to font-object.  Adjusted
for the format change of font-object.
(uniscribe_otf_capability): Adjusted for the change of struct
font.
(add_opentype_font_name_to_list): Don't downcase names.
(uniscribe_font_driver): Adjusted for the change of struct
font_driver.
