bpftool: Adjust for error codes from libbpf probes Originally [1], libbpf's (now deprecated) probe functions returned a bool to acknowledge support but the new APIs return an int with a possible negative error code to reflect probe failure. This change decides for bpftool to declare maps and helpers are not available on probe failures.
