feat(buildozer): build with --release=config

[jmelahman]

Bazel's buildtools get their versioned stamped when --config=release is used as defined in their .bazelrc. (This also builds with -c opt which is also generally nice.)

Since their status.py calls git describe, I needed to clone the repo rather than just download the tarball.
