[PATCH 4/5] perf report: Add report.percentage config option

[Namhyung Kim]

Add report.percentage option for setting default value of the
symbol_conf.filter_relative.  It affects the report output only if a
filter applied.

An user can write .perfconfig file like below to show absolute
percentage of filtered entries by default:

  $ cat ~/.perfconfig
  [report]
  percentage = absolute

And it can be changed through command line:

  $ perf report --percentage relative
