gh-118331: Fix test_list.ListTest.test_no_memory under trace refs build (#130921)

Fix `test_list.ListTest.test_no_memory` under trace refs build

Memory allocation ends up failing in _PyRefchainTrace(), which produces
different output. Assert that we don't segfault, which is the thing
we want to test and is less brittle than checking output.
