[macro] do not use dependency file as file for macro created modules

TODO:

• [x] add test demonstrating how things were going wrong
• [x] use something clean as "fake file"? not sure what right now

Hmm yes, this makes sense. Perhaps it would be a good idea to enumerate these files so that we can be sure the file keys are unique? I'm not sure in which cases this is actually relevant, but that seems like a good idea either way.

For sure; though do you have an idea how to actually implement that? (or a starting point)

Printf.sprintf "file_%i_%i" com.compilation_step com.some_counter would be my first idea.
