Sync Buildbot steps config from saltfs

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [ ] `./mach build -d` does not report any errors
- [ ] `./mach test-tidy` does not report any errors
- [x] These changes are part of https://github.com/servo/saltfs/issues/316

<!-- Either: -->
- [ ] There are tests for these changes OR
- [x] These changes do not require tests because they just copy the steps configuration

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->

Now that our Buildbot configuration is successfully able to read the
steps configuration from the main servo repo and run builds, sync the
steps in the servo tree to match the latest steps.yml from the saltfs
repo.
