Good work! I think this can help solve #45193[1].

And there're still some issues I mentioned in that issues.

1. We may need to fix `wrap-qt-program` in qt-utils.scm. It's
implementation is quite weird(See my reply in [1]). Or we can remove
this function and make package use

  (assoc-ref qt-build-system:%standard-phases 'qt-wrap)

instead.

2. We should search directories in outputs, now we just search all
inputs. Some Qt programs were deployed with a bundle of Qt plugins in
their prefix. If we miss these dirs, they won't run.
