zuul: clean up job definition

This cleans up the zuul job definition:
- moves the 'irrelevant-files' list from project.yaml to
  legacy-sushy-jobs.yaml so that it isn't duplicated
- adds more irrelevant files to the list
- removes requirements.txt from the list of irrelevant files, since
  we want the job to run if this file changes
- reorders the job definition so that the irrelevant-files and
  required-projects are first. This makes it more consistent
  with the other ironic-related projects
