This fixes #1084

I couldn't see a good way to test this change, it would probably need a separate GitHub action job to generate code for a subset of the libraries which seems pretty heavy handed, but let me know if you think that's necessary or there's a better way.

In regard to your code changes in GirTool I found nothing to improve, great work :-).

Looking at the code after some pretty long time I don't like what I did there originally. It is a little bit to hard to grasp what is happening for my feeling. But it is like it is. Perhaps it will see some improvements over time.

Please remove the GModule-2.0.gir from the list of generated projects in GenerateLibs.fsx, it is currently not needed. (Just remove your last commit to avoid adding an additional commit.)

After this change the PR is good to go.

OK thanks, I've removed the GModule-2.0.gir project now.
