Here's a quick POC doing this.

It filters out all identifiers marked 'hidden from the syntax-exports
and variable exports lists in ##sys#finalize-module.

It doesn't touch the indirect exports list. I'm not sure how that should
be handled.

Applies to the 4.12.0 tarball.

If you think this is a valid approach I can clean it up and add some tests.
