perf core: Allocate perf_event in the target node memory

Browse source

For cpu events, it'd better allocating them in the corresponding node
memory as they would be mostly accessed by the target cpu.  Although
perf tools sets the cpu affinity before calling perf_event_open, there
are places it doesn't (notably perf record) and we should consider
other external users too.
