Quick fix for accidentally *fixing* @build deps

In version v0.73.55 we accidentally fixed one half of a bug
that previously would not add dependency objects to @build
methods of classes.

Fixing the other half of the bug would potentially cause behavior
changes in image.imports, so this fix simply re-breaks deps generation
inside of containers to not cause errors
