[ovs-dev] [PATCH v3] python-windows: Update python3 environment variables on Windows

[Alin Gabriel Serdean]

Starting from Python 3.6 two new environment variables have been introduced
on Windows:
PYTHONLEGACYWINDOWSFSENCODING
https://docs.python.org/3/using/cmdline.html#envvar-PYTHONLEGACYWINDOWSFSENCODING
PYTHONLEGACYWINDOWSSTDIO
https://docs.python.org/3/using/cmdline.html#envvar-PYTHONLEGACYWINDOWSSTDIO

To keep backwards compatibility when running tests under Windows we define and
set the two variables thus ensuring default filesystem encoding (mbcs).

Fixes tests on Python version >=3.6:
2030: simple idl, writing via IDL with unicode - Python3
2032: simple idl, writing via IDL with unicode - Python3 - register_columns
2034: simple idl, writing via IDL with unicode - Python3 - tcp
