Add packaging checks to validate component existence

[mjwolf]

What does this PR do?

In packaging tests, add a check to each packaged artifact to validate that all the expected components, and no extras, exist in the artifact for the package variant which is being validated.

FIPS packages are not included in the new checks, as they already have a more sophisticated check in func checkFIPS, and a different list of components.

Why is it important?

If the built artifacts are unexpectedly missing a component, or have an extra unexpected component, it will now be caught in tests.
