Andrii Nakryiko ae2df72314 libbpf: Fix BTF header parsing checks ...

[ Upstream commit c825f5fee1 ]

Original code assumed fixed and correct BTF header length. That's not
always the case, though, so fix this bug with a proper additional check.
And use actual header length instead of sizeof(struct btf_header) in
sanity checks.
