Update and make more consistent the specification of Python package building. Since SCons can be run by Python 3 now, we cannot assume that the Python running SCons is Python 2. This changes a bunch of assumptions in SConstruct about where things should be built or installed. This commit addresses those assumptions by making the options for Python 2 and Python 3 symmetric.
