selftests/bpf: Move test_lwt_ip_encap to test_progs

test_lwt_ip_encap.sh isn't used by the BPF CI.

Add a new file in the test_progs framework to migrate the tests done by
test_lwt_ip_encap.sh. It uses the same network topology and the same BPF
programs located in progs/test_lwt_ip_encap.c.
Rework the GSO part to avoid using nc and dd.

Remove test_lwt_ip_encap.sh and its Makefile entry.
