libxft: fix Freetype header inclusion

Freetype 2.5.1 changes the location of the header files but as directly
including the files isn't recommended they don't see this as a problem.  Change
libxft to use the recommended macros instead of direct inclusion, to fix the
compilation.

+Subject: [PATCH] xftglyphs: use recommend freetype inclusion
+
+FreeType recommends to use their special macros to include the headers, because
+it gives them the ability to move headers around.  They did this in 2.5.1 (yes,
+a point release) and this direct inclusion doesn't work anymore.
