os/exec: use a TestMain to avoid hijacking stdout for helper commands The previous implementation of helperCommand relied on running a well-known Test function which implemented all known commands. That not only added Skip noise in the test's output, but also (and more importantly) meant that the commands could not write directly to stdout in the usual way, since the testing package hijacks os.Stdout for its own use. The new implementation addresses the above issues, and also ensures that all registered commands are actually used, reducing the risk of an unused command sticking around after refactoring. It also sets the subprocess environment variable directly in the test process, instead of on each individual helper command's Env field, allowing helper commands to be used without an explicit Env. Updates #50599. (Also for #50436.)
