Revert 'perf evlist: Fix creation of cpu map'
The commit 55261f46702c ("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.
