perf tools: Pass whole attr to event selectors
Since commit 69aad6f1(perf tools: Introduce event selectors), only perf_event_attr::type and ::config are passed to event selector, which makes perf tool not work correctly. For example, PEBS does not work because perf_event_attr::precise_ip is not passed to the syscall.
