xdp_redirect_map.c is a bpf program used by test_xdp_veth.sh, which is not
handled by the generic test runner (test_progs). To allow converting this
test to test_progs, the corresponding program must be updated to allow
handling it through skeletons generated by bpftool and libbpf.
Update programs section names to allow to manipulate those with libbpf.

test_xdp_veth.sh tests that XDP return codes work as expected, by bringing
up multiple veth pairs isolated in different namespaces, attaching specific
xdp programs to each interface, and ensuring that the whole chain allows to
ping one end interface from the first one. The test runs well but is
currently not integrated in test_progs, which prevents it from being run
automatically in the CI infrastructure.
Rewrite it as a C test relying on libbpf to allow running it in the CI
infrastructure. The new code brings up the same network infrastructure and
reuses the same eBPF programs as test_xdp_veth.sh, for which skeletons are
already generated by the bpf tests makefile.

The new code has been tested in an aarch64 qemu instance:
Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED
I have also checked that some minor alterations in the network
configuration (altering the redirect map, or not loading one of the xdp
programs) make the test fail.
On my testing setup, the test takes a bit more than 3 seconds to run on
average.
Changes in v4:
- add missing close_netns in error path
Changes in v3:
- fix doc style in the new test
- collect acked-by tag
Changes in v2:
- fix many formatting issues raised by checkpatch
- use static namespaces instead of random ones
- use SYS_NOFAIL instead of snprintf() + system ()
- squashed the new test addition patch and the old test removal patch
