Revert 'perf evlist: Fix creation of cpu map'
The commit 55261f46 ("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.
