Truly minimal RTT to userspace eBPF ringbuffer implementation. This
breaks a lot of things - no RTTs are currently recorded or acted
upon. The goal is to measure the scale of the load hit for receiving
these events.

It's not quite done yet, but I spent the last 2 hours matching observed RTT, checking with Wireshark, and looking to see if the numbers line up. Implements a small buffer for RTT values per flow. Shrinks some stack entries. Will require a map rebuild.

More cleanup and logic improvements based on observation. In particular, flow cleanup is more accurate now, and we're a bit more aggressive in what RTT data we accept.
