Include a test to guarantee open() syscalls

[RafaelGSS]

In the #799 issue, we are adding a statement that we trust on every opened file that's documented. To make this statement stronger, might make sense to include a test using eBPF for Linux (not sure about other platforms) that will guarantee the list of opened files, thus making the dependencies update slightly smooth.

This issue is stale because it has been open many days with no activity. It will be closed soon unless the stale label is removed or a comment is made.

I think the idea of a test validating that we only open expected files is a good one. Maybe that should be one of the things we include in the initiatives for this year?

Sure, I was working on it. I had to stop due to other priorities.
