[issue8292] Incorrect condition test in platform.py

[A.M. Kuchling]

New submission from A.M. Kuchling <lists at amk.ca>:

While looking at #4440, I grepped for similar problems and found one in
platform.py in the following line:

if no_os_uname or not filter(None, (system, node, release, version, machine))

In 3.x, filter() returns an object, not a list, so 'not filter()' will always be false.  

One fix is to either convert filter's output by adding list() or tuple(). Another fix could be 'not any ((system, node, release, version, machine))', but I don't know if platform.py is trying to stay compatible with versions of Python that lack any().
