feat(besadii): Propagate Gerrit change ID & patchset to Buildkite r/1122

I previously implemented this in a CL that ended up being abandoned,
but it turns out we need it for the hook setup, anyways.

These environment variables become available during the build and,
crucially, to the post-build hooks.
