This adds a few errors that happen when another update/install process is running in parallel. `apt-get update` doesn't handle race conditions well, and `apt-get install` has one as well. This is pre-cursor to another change that enables parallelism in the packer templates to run the `install-*.sh` scripts parallel, as I mentioned in https://github.com/actions/runner-images/discussions/2320
