[PATCH v6 bpf-next 04/14] libbpf: implement BPF CO-RE offset relocation algorithm

This patch implements the core logic for BPF CO-RE offsets relocations. Every instruction that needs to be relocated has corresponding bpf_offset_reloc as part of BTF.ext. Relocations are performed by trying to match recorded "local" relocation spec against potentially many compatible "target" type
