    """Sets up (most) of the environment vars for the emulator.

    General rule of thumbs-
      #1 Do not overwrite the vars setup here later on.
      #2 If the proper var value can be determined without modifying the

      parent_env: typically os.environ
      with_audio: workaround for b/64555657
