selftests: add functionals test for UDP GRO
Extends the existing udp programs to allow checking for proper
GRO aggregation/GSO size, and run the tests via a shell script, using
a veth pair with XDP program attached to trigger the GRO code path.
rfc v3 -> v1:
- use ip route to attach the xdp helper to the veth
rfc v2 -> rfc v3:
- add missing test program options documentation
- fix sporatic test failures (receiver faster than sender)
