hook: flush stdout before restoring stderr redirection There was a similar issue to 8b011ededfb2. If an in-process hook writes to stdout, the data may be buffered. In which case, stdout must be flushed before restoring its file descriptor. Otherwise, remaining data would be sent over the ssh wire and corrupts the protocol. Note that this is a different redirection from the one I've just removed.
