Force hinting when the font lacks its familyname. 

In Type42 or Type11 font embedded in PostScript & PDF, TrueType
sfnt stream may lack `name' table because they are not required.
Hinting for nameless fonts is safer for PDFs including embedded
Chinese fonts. Written by David Bevan, see:

* src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer
by nameless font is given, TRUE is returned to enable hinting.
