libbpf: bpf__find_by_name[_kind] should use btf__get_nr_types()
When operating on split BTF, btf__find_by_name[_kind] will not iterate over all types since they use btf->nr_types to show the number of types to iterate over. For split BTF this is the number of types _on top of base BTF_, so it will underestimate the number of types to iterate over, especially for vmlinux + module BTF, where the latter is much smaller. Use btf__get_nr_types() instead.
