Landlock: Test, comment and doc improvements

Hi,

This series contains various unrelated improvements I stashed while working on pathname Unix socket scopes (I will send the series for that tomorrow). Only test/comment/doc changes.

I was planning to include this in the upcoming Unix socket scope series but I thought maybe it would be better to send them separately, as they would be unrelated to the main topic of that series.

example
selftests/landlock: Use scoped_base_variants.h for ptrace_test
landlock: Improve the comment for domain_is_scoped
