perf evsel: Introduce per cpu and per thread open helpers
Abstracting away the loops needed to create the various event fd handlers.
The users have to pass a confiruged perf->evsel.attr field, which is already
usable after perf_evsel__new (constructor) time, using defaults.
Comes out of the ad-hoc routines in builtin-stat, that now uses it.
Fixed a small silly bug where we were die()ing before killing our
children, dysfunctional family this one 8-)
