Yep, I don't quite see the problem, but I don't have the years of
experience in terms of packaging you have, either. (NB: I use various
--libdir and --bindir combinations that for some of packaging of PG I
maintain for pg_upgrade, but that's not as complex as Debian, I
guess).

If you can solve that, my take is that it could make things nicer in
the long-run for some of the TAP test facilities. Still, I'll try to
look at a solution for this thread that does not interact badly with
what you are doing, and I am going to grab your patch when testing
things.
