perf stat: Remove transaction_run from shadow update/print code

It's no longer needed, because we use nameid to recognize transaction
events.

Keeping it only in stat code to initialize transaction events.

I.e. struct perf_stat::id, accessible via evsel->priv, will be only set
for transaction related events.
