yacc.c: fix #definition of YYEMPTY
When generating a C parser, YYEMPTY is present in enum yytokentype but
there is no corresponding #define like there is for the other values.
There is a special case for YYEMPTY in b4_token_enums but no
corresponding case in b4_token_defines.
* data/skeletons/c.m4 (b4_token_defines): Do define YYEMPTY.
