Cleans up flake8 rules, per review

@dachary pointed out a few touch-ups. In particular, the change to
`ossec_urls.py` was a nice catch, in that the "noqa" line was ignoring
*all* flake8 violations, not merely the specific one mentioned. @dachary
further pointed out that it wasn't E405, but rather F405, that should
have been permitted.
