``make test`` is failing with traceback

cd tests/fsm && bash run-test.sh
+ arachne_pnr=../../bin/arachne-pnr
+ rm -rf temp
+ mkdir temp
+ python generate.py
Traceback (most recent call last):

This is using today's tip. (52e69ed207342710080d85c7c639480e74a021d7)

Running it on arch, where python actually is python3. That probably makes a difference.

Fixed (finally) in #116. make test should now run on both Python2 and Python3.
