Fix filestuff.c build error if RLIMIT_NOFILE not defined.

Not all systems supporting getrlimit also support RLIMIT_NOFILE
(Eg. All LynxOS systems appear to be lacking support for this).
So check its existance before using it.

gdb/ChangeLog:

        * common/filestuff.c (fdwalk): Add "defined(RLIMIT_NOFILE)"
        preprocessor check.
