Claire Jensen 7473ee56db perf test: Add checking for perf stat CSV output.
Counts expected fields for various commands. No testing added for
summary mode since it is broken.

An example of the summary output is:

         summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
,,,,,1.37,stalled cycles per insn

This should be:

         summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
         summary,,,,,,1.37,stalled cycles per insn

The output has 7 fields when it should have 8. Additionally, the newline
spacing is wrong, so it was excluded from testing until a fix is made.

Committer testing:

  $ perf test "perf stat CSV output"
   88: perf stat CSV output linter                                     : Ok
  $

  $ perf test -v "perf stat CSV output"
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
   88: perf stat CSV output linter                                     :
  --- start ---

  $

I did a s/parnoia/paranoid/g on the [Skip] lines.
