Fix valgrind harness for expected-failure tests Failure-path tests were masking valgrind leak reports because --error-exitcode=42 was being treated as the expected non-zero exit code. Add an expect_failure flag so these tests run valgrind with --leak-check=no, while still checking ERROR SUMMARY for real memory errors. Populate CLI output from stdout/stderr so valgrind output is visible to postfix_check, and only print the captured test output when a test fails. closes https://github.com/official-stockfish/Stockfish/pull/7081 No functional change
