Run AWS test using osbuild worker code

The `osbuild-image-tests` code does a good job testing image builds for
AWS, but it doesn't use the same code paths that a customer would when
using `composer-cli`.

Add a test that builds a compose and uploads the image using
osbuild-composer and its worker. Also, build an instance in AWS based on
the image we imported and check to see if the smoke test file is
present.
