I went down this route because I figured the installer binary should be in `check_deps`. The result: - Add thin wrapper scripts for `buildozer` and `bazel`, similar to the `buildifier` wrapper that's already there. - These are mainly to avoid deduplicating logic, and dodging intricacies of Python imports that I don't understand well through instead subprocessing. - Fix update_roots.py (it was missing a `.parent`, must've been relocated without a re-run at some point) - Fix fuzzer proto code to be `testonly` - Update the `check_deps` targets
