Remove useless pylint error suppression directives (#7657)

As pylint is evolving, it improves its accuracy, and several pylint error suppression (`# pylint: disable=ERROR) added in certbot codebase months or years ago are not needed anymore to make it happy.

There is a (disabled by default) pylint error to detect the useless suppressions (pylint-ception: `useless-suppression`). It is not working perfectly (it has also false-positives ...) but it is a good start to clean the codebase.

This PR removes several of these useless suppressions as detected by the current pylint version we use.

* Remove useless suppress

* Remove useless lines
