bpftool needs to know about the newly introduced BPF_CORE_TYPE_MATCHES relocation for its 'gen min_core_btf' command to work properly in the present of this relocation. Specifically, we need to make sure to mark types and fields so that they are present in the minimized BTF for "type match" checks to work out. However, contrary to the existing btfgen_record_field_relo, we need to rely on the BTF -- and not the spec -- to find fields. With this change we handle this new variant correctly. The functionality will be tested with follow on changes to BPF selftests, which already run against a minimized BTF created with bpftool.
