cppcheck: Remove unused knownConditionTrueFalse suppression

I can't get this warning to trigger, so I think this suppression must be
out of date.  Whether that's because we've changed our code to no longer
have the problem, or because cppcheck itself has been updated to remove a
false positive I don't know.

If we find that we do need a suppression like this for some cppcheck
version, we should replace it with an inline suppression so it's clear
what exactly is triggering the warning.
