perf cpumap: Add CPU to aggr_cpu_id
With no aggregration, such as 'perf stat -A', the aggr_cpu_id lacks a
way to describe per CPU aggregation and the core is set to the CPU in
places like print_counter_aggrdata in stat-display.c.
Setting the core to the CPU is undesirable as the CPU will exceed valid
core values and lead to confusion. Add a CPU variable to address this.
