When the evlist is expanded the metric leader wasn't being updated. As
the original evsel is deleted this creates a use-after-free in
stat-shadow's prepare_metric. This was detected running the "perf stat
--bpf-counters --for-each-cgroup test" with sanitizers.
The change itself puts the copied evsel into the priv field (known
unused because of evsel__clone use) and then in a second pass over the
list updates the copied values using the priv pointer.
Fixes: d1c5a0e86a ("perf stat: Add --for-each-cgroup option")
