perf report: Add report.group config option

Add report.group config option for setting default value of event
group view.  It affects the report output only if perf.data contains
event group info.

A user can write .perfconfig file like below to enable group view by
default:

  $ cat ~/.perfconfig
  [report]
  group = true

And it can be disabled through command line:

  $ perf report --no-group
