lang/python{27,3*}: Backport patch in upstream issue20397

In certain situations, file references (.py[co]) for Python files that
fail to compile with compileall() are still added to distutils --record
output.

This output is used for pkg-plist generation and must only contain
references to files that will be installed.

One example of a failure condition is when a Python 2/3 compatible
package containing a file containing Python 3.x only code is built with
Python 2.x, such as Gunicorn's _gaiohttp.py [1]

This change backports patches submitted against upstream issue 20397 [2]
that has not yet been committed.

 - For Python 2.7 and 3.5, backport both install_lib and test
 - For Python 3.2, 3.3 and 3.4, only backport install_lib

Thank you to Brendan Molloy for producing and submitting the patches
against upstream sources.
