Subject: [PATCH v3 2/2] perf test: Add CVS summary test

The patch "perf stat: Align CSV output for summary mode" aligned
CVS output and added "summary" to the first column of summary
lines.

Now we check if the "summary" string is added to the CVS output.

If we set '--no-cvs-summary' option, the "summary" string would
not be added, also check with this case.
