ci: Unify more of hack/ and tests/

A key thing for me is that the `Justfile` should be a one-stop
shop for development of the project. It can't have everything but
it should answer the basic questions of "how do I build and test
this project".

This aligns the recently added tmt-on-GHA flow a *bit* more closely
with some of that. Biggest is to use the `just build-integration-test-image` as the canonical
way to build a container image with our testing stuff in it;
which uses our main Dockerfile

Other cleanups:
- Change the scripts to accept data via argv[1] and not environment
- Drop the hardcoded testing directory and use `target/` as
  a generic build artifact dir
