Simple fix for DOS7 canonicalize path

[Jukka Heinonen]

This patch provides partial support for DOS7 canonicalize path
function. Full support would require much more effort, but
this fix is enough to make Red Alert Aftermath installer
working.




Changelog:
  Implement DOS7 canonicalize path function as a conversion
  to short file name.
