perf tools: Emit clearer message for sys_perf_event_open ENOENT return
Resend of patch sent back in January 2011 in light of recent confusion around
unsupported events for a given platform.
Improve sys_perf_event_open ENOENT return handling in top and record, just
like 5a3446b does for stat.
Retry of Arnaldo's patch using ui_warning instead of die which allows the
fallback from hardware cycles to software clock.
