Bug in experimental outputs queue empty recovery strategy

[incertum]

In the underlying tbb queue implementation there appears not to be a good way to remove items from the queue. I tested the empty recovery strategy more and mostly it is hanging, but I have also seen a segfault once or a free(): invalid pointer. Therefore, root cause or issues are inconclusive similarly to how we started observing issues with the queue when using the now deprecated -d option. Just keeping the option that mirrors kernel-side event drops when the buffer between kernel space and user space is full makes the most sense.

Proposing to including the fix this in the Falco 0.36.1 patch release.

I agree, we can include it in Falco 0.36.1. Thank you for the fix!
