tf-runner base images

[ilithanos]

@milas thanks for creating this issue, and thanks for offering to help, we could use all the help we can get currently, as the two original maintainers are out looking for work, and that leaves some big shoes to fill for the rest of us.

This issue highlight some structural issues that I wasn't currently aware of.

Currently the actual runner images build and released are build based on the docker files and source code within the tofu-controller repository.

I remember talk about moving the runners out of this repo, but that move hasn't been done yet.

So the way it currently finds the binary is from within this repository.

When looking over the release-runners action i did notice some old references to weaveworks that could be creating some errors.
