Init buildbot-nix with x86_64-linux worker

• depends on Init grafana, take II #149

The flake lock changes are a bit suspicious, I thought I already bumped those inputs.
Is this due to a rebase that undid some of those bumps?

this branch isn't rebased on develop (yet). i only opened the PR to test buildbot-nix webhooks and builds.

i was going to finish #143 and then rebase this PR. now that you closed that without merging, how do you want to proceed here?

I didn't close it, I thought you did.

Probably github did that instead of changing the base branch?

I think we can just reopen it.
