tests/_runner.lua: Allow non-step based tests
The current _runner.lua expects a table containing steps to be passed in. However, not all tests look like this. This commits adds an API to the runner that allows tests to run however they like. They just have to call run_direct() initially and call done() when they are finished. Signed-off-by: Uli Schlachter <psychon@znc.in>
