 Basic Python 3 support for testsuite driver (Trac #9184)

 Summary:
 Most of the changes is adaptation of old Python 2 only code.
 My priority was not breaking Python 2, and so I avoided bigger
 changes to the driver. In particular, under Python 3 the output
 is a str and buffering cannot be disabled.

 To test, define PYTHON=python3 in testsuite/mk/boilerplate.mk.

 Thanks to aspidites <emarshall85 at gmail.com> who provided the initial
 patch.

 Test Plan: validate under 2 and 3
