Don't use LCD antialiasing if Fontconfig doesn't support hinting
Some Freetype implementations (like the one packaged with Fedora) do
not support hinting due to patents 6219025, 6239783, 6307566, 6225973,
6243070, 6393145, 6421054, 6282327, and 6624828; the latest one expires
10/7/19. This makes LCD antialiasing very ugly, so we instead fall back
on NORMAL antialiasing.
