perf list: Avoid confusion of perf output and the next command prompt
Distinguish the output of 'perf list --list-opts' or 'perf --list-cmds'
with the next command prompt, which also happens in other cases (e.g.
record, report ...).
Example:
Before this patch:
$perf list --list-opts
--raw-dump $ <-- the output and the next command prompt are at
the same line
After this patch:
$perf list --list-opts
--raw-dump
$ <-- the new line
