 Tor doesn't need Python to build, but several of our tests require Python
 to run.

 Python 2 will reach end of life on Jan 1 2020 (see
 https://pythonclock.org/).  Let's help it out by:
    * Making our configure script only detect python 3 as a usable python.
    * Removing gross python2 workarounds from our scripts.
