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
