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.
