selftests/bpf: Add test for bpf_skb_change_tail on csum partial skbs
Add a test which builds an ICMP error out of a TCP segment. A tcx prog
on the client's egress side trims the first data segment down to the
target size and pushes the ICMP error headers in front of it to then
reflect the packet back to the sender.
