Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "Directly Run Anteater Docker Container"
  - Directly Run Anteater Docker Container

    The current approach is to run /bin/bash in a fully privilaged docker
    container as the root user and exec the anteater command from this.

    There are a couple of reasons this approach doesn't make sense:

    1) anteater is not a long running service
    2) anteater doesn't need any privilaged access to the host
    3) anteater is already a compiled binary and can be ran directly

    Because the anteater container doesn't need access to all the host
    devices nor is it running docker containers inside of docker, the
    `--privileged=true` flag can be removed.

    Note: '--rm' is added as well to ensure volumes do not persist past the
    container lifecycle and lead to build server running out of disk space.
