Loosen when LBDataRestartReader is created

[lifflander]

Describe the bug
Right now the condition is far too specific.

bool Runtime::needLBDataRestartReader() {
  #if vt_check_enabled(lblite)
    if (arg_config_->config_.vt_lb_data) {
      auto lbNames = vrt::collection::balance::get_lb_names();
      auto mapLB = vrt::collection::balance::LBType::OfflineLB;
      if (arg_config_->config_.vt_lb_name == lbNames[mapLB]) {
        return true;
      }
    }
  #endif
  return false;
}
