Add support for local builds

Not everybody wants to use Docker to build artifacts, or in some cases like in a CI pipeline it may be undesirable.

We should add support for some sort of `--local-build` flag that, if the system is compatible (Amazon Linux 2 only?), it has the proper set of commands to bootstrap the build environment and package the artifacts.

The issue names no files, tests, or entry points. Start by tracing the existing Docker-based artifact build and packaging flow, then define the supported local environment and the behavior of a --local-build flag; done means compatible systems can bootstrap the build environment and package artifacts without Docker.
