rally: verification subunit2json fail to open result file

Command "rally verify start" gives the following error:

TRACE rally   File "/usr/lib64/python2.7/site-packages/rally/verification/verifiers/tempest/subunit2json.py", line 113, in stopTestRun
TRACE rally     with open(self.results_file, 'wb') as results_file:
TRACE rally TypeError: coercing to Unicode: need string or buffer, int found

For Python 2.x, open() requires a string but not file descriptor number.
However for Python 3.x, open() can either accept a string file name of a
file descriptor number.

So modify code to pass in open() string file name.  This should work
for both Python 2.x and 3.x
