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
