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.
