perf report: Fix the output for stdio events list
Changing the output header for reporting forced groups via --groups
option on non grouped events, like:
$ perf record -e 'cycles,instructions'
$ perf report --stdio --group
Before:
# Samples: 24 of event 'anon group { cycles:u, instructions:u }'
After:
# Samples: 24 of events 'cycles:u, instructions:u'
