Test helper functions mktmpfifo and chtmpdir were written before t.Cleanup was available, which necessitated returning of a cleanup function and the use of defer. Let's use t.Cleanup (available since Go 1.14) and simplify the callers. While at it, - use t.Helper (added in Go 1.9); - simplify some error messages (errors that come from os package usually doesn't need to be wrapped).
