[PULL 03/18] tests: print newline after QMP response in qtest logs

[Dr. David Alan Gilbert (git)]

From: Daniel P. Berrangé <berra...@redhat.com>

The QMP commands have a trailing newline, but the response does not.
This makes the qtest logs hard to follow as the next QMP command
appears in the same line as the previous QMP response.
