Ian Rogers 114d0e5b99 perf metrics: Avoid segv if default metricgroup isn't set 
commit e2b005d6ec0e738df584190e21d2c7ada37266a0 upstream.

A metric is default by having "Default" within its groups. The default
metricgroup name needn't be set and this can result in segv in
default_metricgroup_cmp and perf_stat__print_shadow_stats_metricgroup
that assume it has a value when there is a Default metric group. To
avoid the segv initialize the value to "".

Fixes: 1c0e47956a ("perf metrics: Sort the Default metricgroup")
