Ignore pyflake false alarms for python2/3 compatability

We have a few 'if python2 do X, if python3 do Y' spots to have compatability with both versions. Pyflakes understandably complained about not having long, unicode, or raw_input under python3... https://trac.torproject.org/projects/tor/ticket/14559 Adding these to our ignore pattern. Now running the tests under python3 with pyflakes and pep8 the static checks pass.
