POSIX/src/common/module.c: do not use strerror_r the GNU way.

From the manpage:
       char *strerror(int errnum);

       int strerror_r(int errnum, char *buf, size_t buflen);
                   /* XSI-compliant */

       char *strerror_r(int errnum, char *buf, size_t buflen);
                   /* GNU-specific */

So changed the strerror_r() version to a version where we ignore the
the result of the function call
