strchrnul: work around cygwin bug

A misplaced * means that cygwin 1.7.9 dereferences NULL rather
than returning the location of the trailing NUL byte.

* doc/glibc-functions/strchrnul.texi (strchrnul): Document bug.
* m4/strchrnul.m4 (gl_FUNC_STRCHRNUL): Detect it.
* m4/string_h.m4 (gl_HEADER_STRING_H_DEFAULTS): New witness.
* modules/string (Makefile.am): Substitute it.
* lib/string.in.h (strchrnul): Use it.
