Andrii Nakryiko ea4128eb43 selftests/bpf: Add libbpf's log fixup logic selftests
Add tests validating that libbpf is indeed patching up BPF verifier log
with CO-RE relocation details. Also test partial and full truncation
scenarios.

This test might be a bit fragile due to changing BPF verifier log
format. If that proves to be frequently breaking, we can simplify tests
or remove the truncation subtests. But for now it seems useful to test
it in those conditions that are otherwise rarely occuring in practice.

Also test CO-RE relo failure in a subprog as that excercises subprogram CO-RE
relocation mapping logic which doesn't work out of the box without extra
relo storage previously done only for gen_loader case.
