Subject: [PATCH RFC bpf-next 51/52] selftests/bpf: fix using test_xdp_meta BPF prog via skeleton infra

progs/test_xdp_meta works fine when loading via iproute2, but the
skeleton infra can't load it, saying that the types of the BPF
programs present in the binary are not set.
This is due to that the convention is to place XDP progs in the
section which named 'xdp' and TC BPF progs in the section 'tc',
so do it here as well.

Fixes: 22c8852624fc ("bpf: improve selftests and add tests for meta pointer")
