Do not use FT_LOAD_TARGET_LCD when full hinting is requested

Browse Source 
In FreeType 2.8.0 FT_LOAD_TARGET_LCD is now a variant of
FT_LOAD_TARGET_LIGHT instead of of FT_LOAD_TARGET_NORMAL. This means
requesting it will get us light hinting.

See https://sourceforge.net/projects/freetype/files/freetype2/2.8

We should just avoid using it all together since we request the LCD
mode separately anyway with FT_RENDER_MODE later.
