Include foremanctl builds in base build

[ekohl]

What changes are you introducing?

For previews we create a "base" build and then a "new" build. The diff between those is shown. In b27cba4 the foremanctl builds were added to the "new" part, but the "base" part was forgotten.

Why are you introducing these changes? (Explanation, links to references, issues, etc.)

b27cba4 forgot this and broke previews.

Anything else to add? (Considerations, potential downsides, alternative solutions you have explored, etc.)
