test: chdir before running go tool, cleanup afterwards.
issue9355 generated a file a.[568] in test/ directory and left it there. For tests like these, it is best to chdir to a test specific directory before generating any temporary files, since the tests are running in parallel and might otherwise race with each other for the same files.
