[PATCHv2 2/3] git-p4 tests: work with python3 as well as python2

[Luke Diamand <luke@diamand.org>]

Update the git-p4 tests so that they work with both
Python2 and Python3.

We have to be explicit about the difference between
Unicode text strings (Python3 default) and raw binary
strings which will be exchanged with Perforce.

Additionally, print always takes braces in Python3.
