[support8785] std::exception, not just isc::Exception is caught

  If std::exception would be thrown anywhere in message processing
  in Dhcp4Srv::run(), we would not catch it. In principle, that
  should never happen, as the Kea code only throws isc::Exception
  derivatives, but maybe some of the system or boost calls could
  throw std::exception.
