Add a minimal py34 test environment

The first step to port Trove to Python 3 is to have a working
"tox -e py34" test to avoid regressions.

This change creates such minimum test environment just by running 3
very simple unit tests which have no dependency. With the change, it
becomes possible to make the py34 gate voting to avoid regressions.

Partially implements: blueprint trove-python3
