tools/bpf: test kernel bpffs map pretty print with struct kind_flag
The new tests are added to test bpffs map pretty print in kernel with kind_flag for structure type. $ test_btf -p ...... BTF pretty print array(#1)......OK BTF pretty print array(#2)......OK PASS:8 SKIP:0 FAIL:0 Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
