perf tools: Handle kernels that don't support attr.exclude_{guest,host}
Just fall back to resetting those fields, if set, warning the user that that feature is not available. If guest samples appear they will just be discarded because no struct machine will be found and thus the event will be accounted as not handled and dropped, see 0c09571.
