30767aae - tests: skip SIGABRT after destroy_process_group:done as gloo shutdown race

tests: skip SIGABRT after destroy_process_group:done as gloo shutdown race When all ranks complete destroy_process_group:done, the test logic succeeded. SIGABRT in a C++ background thread after that point is a known gloo/PyTorch shutdown race, not a test failure. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
