libbpf: Fix accessing BTF.ext core_relo header
Update btf_ext_parse_info() to ensure the core_relo header is present
before reading its fields. This avoids a potential buffer read overflow
reported by the OSS Fuzz project.
Fixes: cf579164e9ea ("libbpf: Support BTF.ext loading and output in either endianness")
