[PATCH] Uses/zig.mk: fix zig-package extraction

[guest-svmhdvn]

Summary

Dependencies listed in build.zon files could be tarballs
that contain:

• a single directory
• multiple files and directories
• hidden files

This patch takes those into account when moving the extracted
contents into zig-packages.

[guest-svmhdvn]

I also notice that Uses/zig.mk is unmaintained. I have a few other fixes/improvements locally that I'd like to submit soon. I am willing to take over maintainership if necessary (I don't have a ports commit bit yet though).

Do you have a concrete example that this patch fixes? What hidden files would need to be considered?

[guest-svmhdvn]

I am trying to port https://github.com/neurosnap/zmx with this patch: {F140747876}. It pulls in dependencies that are tarballs reflecting the above examples in the patch description. Trying to build zmx without this patch fails. I'm sure many other zig projects with a decent number of recursive dependencies will have this issue.
