    makefs: Fix cd9660 duplicate directory names

    Previously we could create cd9660 images with duplicate short (level 2)
    names.

    cd9660_level2_convert_filename used a 30-character limit (for files and
    directories), not including the '.' separator.  cd9660_rename_filename
    used a 31-character limit, including the '.'.  Directory names 31
    characters or longer (without '.') were shortened to 30 characters, and
    if a collision occurred cd9660_rename_filename uniquified them starting
    with the 31st character.  Unfortunately the directory record's name_len
    was already set, so the unique part of the name was stripped off.

    Directories are up to 31 d-characters (i.e., A-Z 0-9 and _); there is no
    provision for a '.' in a directory name.  Increase the name length limit
    to 31 for directories, and exclude '.'s.

    This name mapping and deduplication code is still fragile and convoluted
    and would beenfit from a more holistic effort.
