perf stat: Get correct cpu id for print_aggr

print_aggr() fails to print per-core/per-socket statistics after commit
582ec0829b3d ("perf stat: Fix per-socket output bug for uncore events")
if events have differnt cpus. Because in print_aggr(), aggr_get_id needs
index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be
used to get aggregated id.

Here is an example:

Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has
cpumask 0,18)

  $ perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core sleep 2

Without this patch, it failes to get CPU 18 result.

   Performance counter stats for 'CPU(s) 0,18':

  S0-C0           1            7526851      cycles
  S0-C0           1               1.05 MiB  uncore_imc_0/cas_count_read/
  S1-C0           0      <not counted>      cycles
  S1-C0           0      <not counted> MiB  uncore_imc_0/cas_count_read/

With this patch, it can get both CPU0 and CPU18 result.

   Performance counter stats for 'CPU(s) 0,18':

  S0-C0           1            6327768      cycles
  S0-C0           1               0.47 MiB  uncore_imc_0/cas_count_read/
  S1-C0           1             330228      cycles
  S1-C0           1               0.29 MiB  uncore_imc_0/cas_count_read/
