That sounds good to me. I originally copied that over from
mm/run_vmtests.sh because their they do have an option for disabling TAP
output (if running as non-kselftest)... but I didn't add the knob to do
that here and am not sure when that might be used so might as well
remove it.

I'll go ahead and remove all of the tap style output.

Best,
Bobby
