tests/{ctrl,vty}_test_runner.py: dump stdout/stderr

Browse Source 
From time to time, we're seeing the following error in Jenkins:

----------------------------------------------------------------------
Traceback (most recent call last):
  File ".../tests/vty_test_runner.py", line 70, in tearDown
    raise Exception("Process returned %d" % rc)
Exception: Process returned -9
----------------------------------------------------------------------

Let's dump stdout/stderr of the process to get more information.
