Subject: [PATCH v3 1/2] selftests/bpf: update xdp_redirect_map prog
 sections for libbpf

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.
