test/(functional/probe):Replace python print operator with print function (pep H233, py33)

'print' function is compatible with 2.x and 3.x python versions
Link : https://www.python.org/dev/peps/pep-3105/

Python 2.6 has a __future__ import that removes print as language syntax,
letting you use the functional form instead
