libperf: Add perf_evlist__init() function
Add the perf_evlist__init() function to initialize a perf_evlist struct.
Committer testing:
Fix a change in init ordering that was causing this backtrace:

So move the initialization of the core evlist (calling
perf_evlist__init()) to before perf_evlist__set_maps() in
evlist__init().
