gitlab: Re-Sync sidekiq service launch with upstream

6a4e45c5 (gitlab: Sync sidekiq service launch with upstream) claimed to
sync sidekiq startup with upstream, but missed one upstream change in
between 8.2 and 8.4:

    https://gitlab.com/gitlab-org/omnibus-gitlab/commit/2eb7634f

My bad - I should have reviewed git log for

    https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-cookbooks/gitlab/templates/default/sv-sidekiq-run.erb

and I did not noticed that change because I did not and just compared
queues list visually.

Pick it up.
