Small simplification to textpath.

- verts of glyph_map entries are created with FT2Font.get_path() and are
  thus already arrays; no need to convert them again.
- We can always extend verts and codes regardless of whether verts1 is
  empty (extend will just be a noop in that case); empty verts should be
  exceptional anyways.
