perf list: Fix metricgroups title message

  $ perf list metricgroups

gives

  List of pre-defined events (to be used in -e):

  Metric Groups:

  Backend
  Bad
  BadSpec

But that's incorrect of course because metric groups or metrics can only
be specified with -M. So fix the message to say -e or -M
