[roll third_party/pigweed] pw_unit_test/test_runner: Only debug log on success

Updates the pw_unit_test/test_runner.py and pw_cli/process.py to
ensure that a successful host unit test run does not produce extra
ninja output when using CMake by using debug logs instead of info
logs for successful runs.
