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%
