Namhyung Kim 879d77d0cb Revert 'perf evlist: Fix creation of cpu map' 
The commit 55261f4670 ("perf evlist: Fix creation of cpu map") changed
to create a per-task event when no cpu target is specified. However it
caused a problem since perf-task do not allow event inheritance due to
scalability issues so that the result will contain samples only from
parent, not from its children.

So we should use perf-task-per-cpu events anyway to get the right
result. Revert it.
