Update clang-tidy --fix-errors integration test expectations

With --fix-errors flag, newer clang-tidy versions (15+) return exit code 0
and produce no output for files with unfixable errors. The integration tests
were expecting these to fail, but they should pass.

Updated integration test expectations to match shell command test expectations
and actual behavior.
