progtest: Exit with non-zero status on test failure

Not a very useful test runner if it doesn't ever fail, now is it?

* Makefile.am (check): Invoke new test/runner-test.  Depend on modindex.
* bin/runner.js: Exit with non-zero status on assertion failure.
* test/_stub: Add stub program with good and bad test cases to test
    exit code.
* test/runner-test: Add system test.
