[PATCH 13/19] perf tool: Skip symbols in exclude list while printing callchain
Leverage new exclude symbol list to allow user to not see certain functions
in a backtrace. For example repeating patterns like:
do_select core_sys_select sys_select
can be reduced to just sys_select when dumping callchains, consuming less
real estate on the screen while still conveying the essential message - the
process is in a select call.
