Add templates for derived Key in DBo::CompareById::oprator() [gcc 8]. 

* Change: In Hurricane::DBo::CompareById, starting from gcc 8, the compare
    function is checked inside the STL map<>/set<> so the lhs & rhs arguments
    are of the exact type of the Key, even excluding a base class.
      So now, in complement of the normal function, we provide a templated
    comparison functor in CompareById.
