Use a (mostly) hermetic Python interpreter
It still requires python to be installed on the host to run the wrapper
scripts, but it's close to being fully hermetic.
This also requires/enables the following changes, unfortunately all at
the same time:
* Use a downloaded f2py
* Use a downloaded scipy/numpy/matplotlib
* Fix a few things that don't run with the python version in their #!
* Stop using bazel-generated __init__.py files, because those interfere
with importing matplotlib nicely
