unittests: add a runner to execute all unittests

We'll soon have multiple unit tests, add a runner that will
discover all of them and execute all tests.

It was opted to discover only files that starts with "test",
as this way unittest discover won't try adding libraries or
other stuff that might not contain unittest classes.
