perf tools: Add hist.percentage config option
Add hist.percentage option for setting default value of the
symbol_conf.filter_relative. It affects the output of various perf
commands (like perf report, top and diff) only if filter(s) applied.
An user can write .perfconfig file like below to show absolute
percentage of filtered entries by default:
$ cat ~/.perfconfig
[hist]
percentage = absolute
And it can be changed through command line:
$ perf report --percentage relative
