Do not interpret python2 setup.py using python3

[xsuchy]

I am getting this traceback:

It is probably not correct to interpret python2-like setup.py (especially when run with -b 2) with python3.

I see what is the problem, but it doesn't seem that it is possible to switch interpret using runpy. It will be necessary to redesign extract_distribution module a bit more. I will take a look at this before some of the following releases.

Thank you.
