[PATCH] stat: use pathmax.h only if needed

[Paul Eggert]

* lib/stat.c: Include pathmax.h only if REPLACE_FUNC_STAT_DIR.
This is better for Emacs, which does not have a mingw port and
therefore can avoid the pathmax module.

        utimens: remove dependency on dup2
        * lib/utimens.c (fdutimens): Don't invoke dup2; it's not needed
        to work around the Linux kernel bug.
