Install swiftshader from a commit instead of a submodule (#3634)
For now the install commit that we use is manually matched with the commit in the `swiftshader/Dockerfile`. It would be nice for this script, the `rbe-toolchain/Dockerfile`, and the `swiftshader/Dockerfile` to share a single source of truth in the future.
