[FEAT] full message trail

The fake testmachine did only handle installation. We need more. Now it
sends messages for a whole (successful) test. Installation, bootup,
running one testprogram and done. I don't have a good way to make the
test MCP thinks we execute configurable. Maybe we need to parse the
preconditions in the config somehow.
