    readelf: Break sysv[64] symbol hash bucket chain loops.

    The bucket chain should not contain loops. If it does we should mark the
    hash bucket chain as invalid. This is easily checked by noticing when we
    have seen more than the number of chain elements. Which equals the max
    number as symbols in the table.
