perf stat: Output running time and run/enabled ratio in CSV mode
The information how much a counter ran in 'perf stat' can be quite
interesting for other tools to judge how trustworthy a measurement is.
Currently it is only output in non CSV mode.
This patches make perf stat always output the running time and the
enabled/running ratio in CSV mode.
This adds two new fields at the end for each line. I assume that
existing tools ignore new fields at the end, so it's on by default.
Only CSV mode is affected, no difference otherwise.
v2: Add extra print_running function
v3: Avoid printing nan
v4: Remove some elses and add brackets.
v5: Move non CSV case into print_running
