perf tools: Fix -x/--exclude-other option for report command

Browse Source 
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.
