    cd9660: Unbreak symbolic links
    
    Since the introduction of permission masks, cd9660_getattr() returns a
    size of zero for all symbolic links, because the code to retrieve the
    length of the link target (as required by POSIX) is dead, since we strip
    away the type bits before we try to use them to identify the file as a
    link.  Address this by checking the vnode type instead.
