perf hists: Add missing period_* fields when collapsing a hist entry

So that the perf report won't lost the cpu utilization information.

For example, if there're two process that have same name.

  $ perf report --stdio --showcpuutilization -s pid
  [SNIP]
  #   Overhead       sys        us  Command:  Pid
  #   ........  ........  ........  .............
  #
        55.12%     0.01%    55.10%  noploop:28781
        44.88%     0.06%    44.83%  noploop:28782

Before:
  $ perf report --stdio --showcpuutilization -s comm
  [SNIP]
  #   Overhead       sys        us
  #   ........  ........  ........
  #
       100.00%     0.06%    44.83%

After:
  $ perf report --stdio --showcpuutilization -s comm
  [SNIP]
  #   Overhead       sys        us
  #   ........  ........  ........
  #
       100.00%     0.07%    99.93%
