Update pytype_test to be easier to run manually. (#2469)

Browse Source 
* Moves the pytype installation to requirements-tests-py3.txt, now
  that pytype can run under Python 3.5+.
* Changes tests/pytype_test.py to not require a --python{version}-exe
  argument when it can automatically find the Python interpreter, and
  cleans up a few typos and out-of-date things.
* Updates the appropriate documentation.
* Updates .travis.yml.

Option two will parse the file, mostly syntactical correctness. Option three
will load the file and all the builtins, typeshed dependencies. This will
also discover incorrect usage of imported modules.
