perf tools: Rename cpu_map__all() to cpu_map__empty()
The CPU map is in an "empty" (or not-applicable) state when monitoring specific threads. cpu_map__all() returns true if the CPU map is in this empty state (i.e for the 'empty_cpu_map' or if we created the map via cpu_map__dummy_new(). The name, cpu_map__all(), is misleading, because even when monitoring all CPUs, (eg: perf record -a), cpu_map__all() returns false. Rename cpu_map__all() to cpu_map__empty().
