Prevent packing of native modules

[philrz]

#2914 has the background and repro. The change in this PR is based on what I found in element-hq/element-web#17188 and how they fixed it via https://github.com/vector-im/element-desktop/pull/337/files, since their symptom looks exactly like ours.

I made a Dev build https://github.com/brimdata/zui/actions/runs/7064639612 using the change on this branch and it tested out fine. I used it to repeat the same repro steps shown in the video in #2914 (comment) and none of the .org.chromium.Chromium.* accumulated this time. The app also ran otherwise healthy, and in particular, I was able to import/query data, which is a sign that node-pipe (one of the modules now subject to different packaging) was still working fine, since it's my understanding that the successful launch of the zed serve process is dependent on that.

On my Linux VM I also did a find of the contents below /opt/Zui/resources with GA Zui v1.4.1 and then also with the Dev build just to confirm I saw only the expected differences, and that does seem to be the case.
