internal/rosa/package/rsync: annotate blocked update

Despite rsync being practically feature complete, with minimal changes in many years, it recently had a large number of poor quality AI-generated changes, with the first release including them apparently being 3.4.2. Release 3.4.3 then introduced a dependency on kernel-headers, creating a dependency loop that prevented directly upgrading to it. This change annotates the blockage since it is not worth working around the dependency loop for AI-generated garbage.
