jobs/infrastructure: put template var into same line to prevent invalid yaml

We ended up with

 jobs_blacklisted_from_messages: ""

with the current configuration but the variable needs to be an array.
The previous template didn't allow us to pass an empty array but with
keeping everything on the same line we can now set the variable to []
and generate a valid yaml file.
