fseeko: Add missing declaration on OSF/1 5.1.

* lib/stdio.in.h (fseeko): Test HAVE_DECL_FSEEKO, not HAVE_FSEEKO.
* m4/fseeko.m4 (gl_FUNC_FSEEKO): Test whether fseeko is declared.
* m4/stdio_h.m4 (gl_STDIO_H_DEFAULTS): Initialize HAVE_DECL_FSEEKO.
* modules/stdio (Makefile.am): Substitute HAVE_DECL_FSEEKO.
* doc/posix-functions/fseeko.texi: Mention the OSF/1 5.1 problem.
