test/fdpass.c: skip test that fails on FreeBSD 13.0

The /odd-limit/at test passes on 13.1 and 14.0 images, but fails on 13.1.
Debugging has not given me any useful hints why this may be the case, so
disable this test on 13.0 for now.

This allows us to drop the ci_test_fatal: "no" override which will ensure
that any FreeBSD regressions are caught.
