- Remove the -T from the 4.x newfs as well.

- Don't write out 0xaa55 to the end of the filesystem as md(4) doesn't
  generate that warning and it breaks 'disklabel mdX auto'.
- Use the 'canonical' disk name mdX instead of /dev/mdX to disklabel so
  we can use disklabel auto for mfsroot filesizes that aren't a standard
  size in /etc/disktab.
