We add a syslinux floppy disk type using parts of the genliso script.
This floppy image cat be dd'ed to a physical floppy or used in
instances where a virtual floppy with an mountable DOS filesystem is
useful.
We also modify the genliso script to only generate .liso images
rather than creating images depending on how it is called.
