This adds a 4 argument version of fchmodat (fchmodat4) that
supports a flag argument, as specified by POSIX. It supports
the same two flags as fchownat: AT_SYMLINK_NOFOLLOW and AT_EMPTY_PATH.

I don't think it's possible to emulate AT_EMPTY_PATH in user space, so I wonder if this could be applied, and if not, why. Thanks.
