Thanks for testing. Looks like this fix is cursed. And clearly my perf
test runs are still not working. I usually try to avoid installing perf,
but you have set some symlinks manually and use a special directory
for the shell test to work and that is not reliable here.

I guess we can exclude the two cases for now (perf stat record vs -F +metric), 
although it would be better to make metrics work in both cases.
But changing the stat code to support multiple aggregations at the same
time is too much. Maybe if the perf metric code could also use
AGGR_NONE, but I don't know how to make that work.
