fix boost bind placeholders

for for boost 1.78 eg.:

crocoddyl/unittest/test_contacts.cpp:170:114: error: '_2' was not declared in this scope
  170 |   reevals.push_back(boost::bind(&crocoddyl::unittest::updateAllPinocchio, &pinocchio_model, &pinocchio_data, _1, _2));
      |                                                                                                                  ^~
