don't pick up python2 from PYTHONPATH

$ ./bootstrap.sh

Installing setuptools, pip, wheel...done.
Traceback (most recent call last):

Turned out to be because PYTHONPATH had go/dist/grpc/usr/local/lib/python2.7/site-packages before go/dist/selenium/lib/python3.5/site-packages (3.5 has the missing module).

Setting PYTHONPATH= for that pip install worked for me.
Slightly worried because Alex Charis made some commits about this in February ( f14c0586fc391c8677 , 3a5949bb9ca1440c3e ), so maybe I'm just undoing that.
