    netflow: fix build on MacOS

        This commit adds explicit type casting for ConfigLogger::log_value()
        function call which accepts number of size_t type as an argument.
        The reason is that on MacOS with Homebrew GCC 7.5.0 it cannot resolve
        the call with size_t type to one of the overloads with int parameters.
