Clean up `generic' fields. 

* include/freetype/internal/ftobjs.h (FT_ModuleRec, FT_LibraryRec):
Remove `generic' field since users can't access it.

* src/base/ftobjs.c (FT_Done_GlyphSlot): Call `generic.finalizer' as
advertised in the documentation of FT_Generic.
(Destroy_Module, FT_Done_Library): Updated to changes in `ftobjs.h'.
