No, these should be ripped out. This is because a long time ago everything was in
CSWlibffi and packages depended on it. Then libffi.so.5 was split and the existing
packages should still find their library. As CSWlibffi is still in the catalog as
stub depending on .so.5 it stays where it is. Just remove the three lines.

The problem is that the new .so.6 library got in the catchall package and
CSWlibffi5 was empty as more like libffi6 was generated.

Yep, or „repackage“.
