perf stat: Fix adding multiple event groups
The -M metric group parser threw away the events of earlier groups when
multiple groups were specified. Fix this here by not overwriting the
string incorrectly.
Now this works correctly:
% perf stat -M Summary,SMT --metric-only -a sleep 1
Performance counter stats for 'system wide':

while previously it would only show the SMT metrics.
