Minor clean-ups.

* src/base/ftrfork.c (raccess_make_file_name): Do not set error.
* src/sfnt/sfdriver.c (get_win_string, get_apple_string): Ditto.
* src/cff/cffobjs.c (cff_strcpy): Do not confuse about error.
* src/psaux/psobjs.c (ps_table_done): Ditto.
* src/truetype/ttgxvar.c (ft_var_readpacked*, ft_var_load_avar): Ditto.
