[PATCH 4/4] python: silence pylint raising-non-exception error

[John Snow <jsnow@redhat.com>]

As of (at least) pylint 3.3.1, this code trips pylint up into believing
we are raising something other than an Exception. We are not: the first
two values may indeed be "None", but the last and final value must by
definition be a SystemExit exception.
