Bug#1772: boot, root, base disks need entries in ms-dos tree

["Michael E. Deisher" <deisher@enws428.EAS.ASU.EDU>]

Package: disks
Version: 0.93R6 (Oct 27)

There should be a directory ./debian-0.93/ms-dos/disks with 8.3 names
for the boot, root, and base disks.  Alternatively, the files themselves
could be given 8.3 names since (most of the time) they will be used
on MS-DOS systems.
