Disable ordered_events for report raw dump, because
for raw dump we want to see events as they are stored
in the perf.data file, not sorted by time.

There's no longer need to have test_attr__open inside
sys_perf_event_open call, because both record and stat
call evsel__open_cpu, so we can call it directly from
there and not polute perf-sys.h header.
