Here's a minimal patch like that.

I don't think it's worth back-patching. Only 15 and 16 could possibly
be affected, I think, because the test wasn't enabled before that. I
think this is all just a late-appearing blow-up predicted by the
commit that enabled it:

Enable routine running of citext's UTF8-specific test cases.

These test cases have been commented out since citext was invented,
because at the time we had no nice way to deal with tests that
have restrictions such as requiring UTF8 encoding. But now we do
have a convention for that, ie put them into a separate test file
with an early-exit path. So let's enable these tests to run when
their prerequisites are satisfied.

(We may have to tighten the prerequisites beyond the "encoding = UTF8
and locale != C" checks made here. But let's put it on the buildfarm
and see what blows up.)

Hamerkop is already green on the 15 and 16 branches, apparently
because it's using the pre-meson test stuff that I guess just didn't
run the relevant test. In other words, nobody would notice the
difference anyway, and a master-only fix would be enough to end this
44-day red streak.
