tests: fix dependencies for tests

* Remove the limitation on prospector as the upstream bug was fixed.
* Exclude flake8 from the minimum requirements as we just run the unit
  tests with the minimum requirements.
* This will require the removal of python3-flake8 from the Build-Depends
  on debian/control when doing the next release as flake8 is not needed
  when building the package.
