ftw.c: avoid shadowing warning

[Jim Meyering]

In using the recently-modified ftw.c outside of the GNU libc, I saw
this warning:

  ftw.c:637: warning: declaration of `save_err' shadows a previous local
  ftw.c:511: warning: shadowed declaration is here

I fixed it by renaming the variable in the latter declaration.

        * io/ftw.c (ftw_startup): Rename local-shadowing local to pacify gcc.
