bpf: btf: Add tests for the btf uapi changes
This patch does the followings: 1. Modify libbpf and test_btf to reflect the uapi changes in btf 2. Add test for the btf_header changes 3. Add tests for array->index_type 4. Add err_str check to the tests 5. Fix a 4 bytes hole in "struct test #1" by swapping "m" and "n" Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
