test/: Add three basic self tests

* true-001.sh: Always returns true - this should never ever fail.

* run-test-001.sh: Invokes run-test, passing itself as a parameter.
  Subsequently, it outputs the very same (hardcoded) expected and actual
  values.

* run-test-002.sh: Tests run-test's negative assertion feature in a way
  similar to run-test-001.sh. However, output different (hardcoded)
  expected and actual values and invoke run-test with the negative test
  prefix ('!').
