[cff] Modify an FT_ASSERT.

* src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah
bug #43661, the test font `...aspartam.otf' still triggers an
FT_ASSERT.  Since hintmap still works with count==0, ...
(cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to
suppress the assert.
