CountingOutputStream: properly flush()

If console output limiting is enabled in the actual output stream
is wrapped in a CountingOutputStream to hard-limit the number of
bytes written. As on the console, the two streams, stdout and stderr,
might interleave, proper flushing of writes is important. Therefore,
make sure flushing is propagated through the CountingOutputStream.
