[PATCH 2/3] gdi32: Add the workaround for Freetype<2.8.1 V40 FT_LOAD_TARGET_MONO problem.

[Byeongsik Jeon]

Wine-bug: https://bugs.winehq.org/show_bug.cgi?id=41639
--
Freetype<2.8.1 V40 has the wrong advance width issue, the wrong rendering issue.
This workaround is required for the Linux distribution that contains the old
version of Freetype.

These two patches help Wine resolve issues caused by fragmentation of Freetype
version and build option.

I didn't mean to, but this patch also solves the wine-bug#41639.
This is the patch on the init_freetype(). It's not relevant to my old patch
using the gasp table.
