Switch test from 8.8.8.8:53 to "www.github.com:80"

Radio upgrade: Point updater to a binary which is fully MAVLink 2.0 enabled, including radio status.

This is important to avoid having QGC hijack links that are active (we read 2000 bytes!) but are definitely not MAVLink. This can have nasty side-effects, e.g. if we would talk to an LTE modem in a laptop or alike.

Switch only to MAVLink 2 on first connected link. Fall back to v1 if two links to the same vehicle are connected and one can only do v1
