Extend testing (using mock capture sources)

[fako1024]

Depends on fako1024/slimcap#7 , in which a way of mocking a fully functional capture source is provided.

DoD

• Replace existing mock logic implemented in 71 goprobe rotation runs into deadlock on low traffic interfaces #80 (once the referenced changes are merged)
• Extend tests leveraging the new functionality
• Add E2E test

The good news is that I got a full-blown E2E test to work, including goProbe / goQuery round-trip. The bad news is that the tests did reveal a race condition in the ring buffer mock source which will require some fixing. Since I'll be afk next week I'll probably have to continue after that. @els0r FYI.

I would call that double good news if more rigorous testing reveals previously unknown flaws.

Thanks for letting me know. I'll chip away at #43 in the meantime.
