selftests: net: veth: test peer ndo-xmit after GRO toggle while down

Browse source

Test that toggling GRO on a veth device while it is down updates the
peer's ndo-xmit XDP feature once the device comes up, for both GRO on
and GRO off.

xdp-features is only visible through netlink, so read it with the ynl
CLI, as double_udp_encap.sh does. Skip the checks if the CLI is not
found, as in an installed kselftest tree.
