Merge branch 'selftests-bpf-convert-test_tc_tunnel-sh-to-test_progs'

====================
Hello,
this is the v3 of test_tc_tunnel conversion into test_progs framework.
This new revision:
- fixes a few issues spotted by the bot reviewer
- removes any test ensuring connection failure (and so depending on a
  timout) to keep the execution time reasonable

test_tc_tunnel.sh tests a variety of tunnels based on BPF: packets are
encapsulated by a BPF program on the client egress. We then check that
those packets can be decapsulated on server ingress side, either thanks
to kernel-based or BPF-based decapsulation. Those tests are run thanks
to two veths in two dedicated namespaces.

- patches 1 and 2 are preparatory patches
- patch 3 introduce tc_tunnel test into test_progs
- patch 4 gets rid of the test_tc_tunnel.sh script

The new test has been executed both in some x86 local qemu machine, as
well as in CI:
