[0/6] selftests: Move test output to diagnostic lines

Message

Kees Cook April 9, 2019, 11:55 p.m. UTC

This refactors the selftest Makefiles to extract the test running logic
to be reused between "run_tests" and "emit_tests", while also fixing
up the test output to be TAP version 13 compliant:
- added "plan" line
- fixed result line syntax
- moved all test output to be "# "-prefixed as TAP "diagnostic" lines

The prefixing code includes a fallback mode for limited execution
environments.
