[evas_font_draw.c] Do kerning correctly for word cache.
Technically this should speed it up a little. That's a nice change for a bug

[Evas_Engine_DirectFB.h] Fix header include
The current way of including directfb.h makes it hard for people with multiple
versions of DirectFB installed.
This is the correct way to include that header, and it's the way
ecore_directfb does it.
