tests: fix 250: parse.error=verbose overflow

[Akim Demaille]

On OS X, this test fails with a hard error.  On this machine, the cpp guard for 
stdlib.h is not _STDLIB_H, which I guess it is on GNU/Linux, which would 
explain why we don't have the problem there (since the second inclusion of 
stdlib.h in yacc.c is protected by _STDLIB_H).

Installed in master and branch-2.5.   2.4.3 has no such test.


        * tests/regression.at (parse.error=verbose overflow): Avoid the
        double inclusion of stdlib.h as it triggers hard errors.
