Namhyung Kim 8f08cf3330 perf report: Make --skip-empty as default

so that the compact output is shown by default.  Also add 'report.skip-empty'
config option to override the default.  Users can also use --no-skip-empty
command line option to change the behavior anytime.

Committer testing:

  $ perf report --stat
