Added the rules files `module.mk' to "sfnt", "truetype" and "type1" to 

reflect the new modules/drivers list management performed through the
file `freetype2/config/modules.mk'

Changed the driver header files to reflect the new modules/drivers
list management. We get rid, at last, of the infamous pre-processor
tricks used to build the list at compile time.

`src/base/ftinit.c' is also modified to reflect the changes..
