Fixed the unit numbers of the devfs `fd' devices.

Browse Source 
Made the devfs `fd' devices bug for bug compatible with the ones created
by MAKEDEV:
- ownership is bin.bin, not root.wheel, except for std*.  The devfsext
  interface doesn't seem to allow specifying the ownership of /devfs/fd,
  so it's still incompatible.
- std* aren't links to fd/[0-2].
