This also removes -t from docker run, as we don't actually require a
terminal, this was just muscle memory.
This also archives the artifacts for testing.
This depends on a new entrypoint put inside the docker image, that will
read BUILDER_UID and fix up the users and files.
This also removes "sudo" and allows the entire script to be run with
sudo without messing with the build file permissions.
