Florian Klink 28ef43824b nixosTests.flannel: port to python, unbreak
For reasons yet unknown, the vxlan backend doesn't work (at least inside
the qemu networking), so this is moved to the udp backend.

Note changing the backend apparently also changes the interface name,
it's now `flannel0`, not `flannel.1`

fixes #74941
