Check if we still need to patch the Jenkins puppet service definition

Originally created by @bertagaz on #9683 (Redmine)

We patched the upstream puppet-jenkins module to have a better service definition working with Debian’s Jenkins daemon.

That’s feature/better_service_definition branch of the Tails puppet-jenkins module clone.

But our puppet-module is lagging a lot behind the upstream.

We need to first upgrade this module and check if this change is still relevant. If it is, then we’ll have to upstream it.

Feature Branch: puppet-jenkins:features/9618-stronger_plugin_verification
