Use generated trait

[squakez]

With #4764 we have simplified the managment of native builder execution. However we're not using a best practice as the operator alter the configuration .spec of builder trait by adding something that will be required at build time. In order to follow best practices, we should instead move the generated configuration into the .status.

Ideally, we should have a .status.traits parameter where we copied the .spec.traits and additionally include any operator generated configuration.
