We almost certainly want to support AT_EMPTY_PATH at the same time.
Otherwise userspace will still need to go through /proc when trying to
chmod a file handle they have.
That can't be allowed.
IIUC, fchmodat2(fd, "", m, AT_EMPTY_PATH) is equivalent to fchmod(fd,
m).  With that, new architectures only need to implement the fchmodat2
syscall to cover all chmod variants.
