CaptureInfo.Timestamp is in the future by 40 to 120 ms

On M1 Max MacBook Pro usb Ethernet, every few hours streaks of corrupt timestamps that are in the future appear

I wrote a test executable exposing the problem
* macOS 13.2.1
* arm64 M1 Max
* usb Gigabit Ethernet
* Does not appear on M1 Mac mini cable Ethernet
* gopacket v1.1.19 — Oct 19, 2020

Apple’s own usb driver is garbage, it could be that. It could be M1 Max

code is here: https://codeberg.org/haraldrudell/gofacts/src/branch/main/gopacketstamp#gopacket-timestamps-in-the-future

output:

Suggestions:
* Retain the sec nsec values provides by the operating system so they can be inspected by consumer
* Provide an early sibling Go timestamp to use if OS timestamp corrupt
* fix the bug :)
