perf target: Move the checking of which map function to call into function.
Check for cpu_map__dummy_new() or cpu_map__new() to be called in perf_evlist__create_maps() is more complicated. This patch moves the checking work into target.h, combining two conditions and making perf_evlist__create_maps() more readable.
