It cannot work anyway because host disk cannot be read. This fixes hostfs access on native Windows build where filenames start with '\' or do not have initial separator at all (d:\foo).
Issue was observed when running grub-fstest on Windows. On UNIX image name is canonicalized to always start with `/' so this was not noticed. This has side effect of allowing relative path names on host, but this already was the case with `ls' command, so it just extends it to all commands.
