perf tools: Fix -x/--exclude-other option for report command
Currently we have symbol_conf.exclude_other being set as true every time
so the -x/--exclude-other has nothing to do.
Also we have no way to see the data with symbol_conf.exclude_other being
false which is useful sometimes.
Fixing it by making symbol_conf.exclude_other false by default.
1) Example without -x option:
$ perf report -i perf.data.delete -p perf_session__delete -s parent
+ 99.91% [other]
+ 0.08% perf_session__delete
+ 0.00% perf_session__delete_dead_threads
+ 0.00% perf_session__delete_threads
2) Example with -x option:
$ ./perf report -i perf.data.delete -p perf_session__delete -s parent -x
+ 96.22% perf_session__delete
+ 1.89% perf_session__delete_dead_threads
+ 1.89% perf_session__delete_threads
In Example 1) we get the sorted out data together with the rest
"[other]". This could help us estimate how much time we spent in the
sorted data.
In Example 2) the total is just the sorted data.
