Convert from vnd and installboot.old to Makefile.tarfloppy and MI installboot.

Allow various parameters to be tweaked via external make(1) or
environment variables, to allow for easy creation of floppy sets
containing arbitrary kernels.

XXX: GENERIC still doesn't fit on a single floppy, so this won't build as-is
and is still not enabled by default.  (Per discussion with Ross & Jason.)
