[Win] version.py: ValueError: Version expected to be string, integer, tuple or list of integers

Bug 179426 has added version.py.
It reports the following error by using ActivePython 2.7.

I tested with trunk@224660.

5th element of getwindowsversion() is ''. This causes another error.
Should be truncated like sys.getwindowsversion()[0:3].

r224657 breaks Cygwin Python, too.

This is the output of ver command.

This doesn't return tuple anymore, we should rename it to _win_version_from_cmd.
