Subject: perf c2c: Fix 'perf c2c record -e list' to show the default events
 used

When the event is passed as list, the default events should be listed as
per 'perf mem record -e list'. Previous behavior is:

  $ perf c2c record -e list
  failed: event 'list' not found, use '-e list' to get list of available events

   Usage: perf c2c record [<options>] [<command>]
      or: perf c2c record [<options>] -- <command> [<options>]

      -e, --event <event>   event selector. Use 'perf mem record -e list' to list available events
  $

New behavior:

  $ perf c2c record -e list
  ldlat-loads  : available
  ldlat-stores : available

v3: is a rebase.
v2: addresses review comments by Jiri Olsa.
