[OT] Use general-category, not GDEF class, to decide to zero mark advances 

At this point, the GDEF glyph synthesis looks pointless.  Not that I
have many fonts without GDEF lying around.

As for mark advance zeroing when GPOS not available, that also is being
replaced by proper fallback mark positioning soon.
