Add archetypeCatalog setting of local to prevent repository==null error in generation

[cunningt]

I'm getting the following error in building RC2 locally :

[INFO] --- archetype:3.2.1:generate (generate-my-car-service) @ camel-olingo2 ---

Looking at the documentation for the maven-archetype-plugin generate goal, it looks like <archetypeCatalog/> controls the catalog search and local might be the most appropriate setting?

This change fixed the build error locally for me.
