Subject: Refactor where architecture selection is performed for universal
 binaries

Responsibility for selecting an architecture is moved out of
`UniversalTransform` and into a new `ContainerOpenRequest` class.
`UniversalTransform` still handles architecture selection in headless
operation (for now).
