[truetype] Simplify `trick_names'.

* src/truetype/ttobjs.c (tt_check_trickyness_family): For the case
that the beginning part of a long tricky family name is already
registered as another tricky family name, no need to double-check
the longer one.  Such long tricky family names are removed from
the `trick_names'.
