    cd9660: Fix ISO_SUSP_CFLAG_ROOT handling in RockRidge
    
    When encountering a ISO_SUSP_CFLAG_ROOT element in Rock Ridge processing,
    this actually means there's a double slash recorded in the symbolic
    link's path name.  We used to start over from / then, which caused link
    targets like "../../bsdi.1.0/include//pathnames.h" to be interpreted as
    /pathnahes.h.  This is both contradictionary to our conventional slash
    interpretation, as well as potentially dangerous.
    
    The right thing to do is (obviously) to just ignore that element.
