Sorry about that. Exactly as you guessed the code was missing a check if the tool
event actually has an alias.

Fixed Output:

$ perf list | grep Tool
  duration_time                                   [Tool event]
  user_time                                       [Tool event]
  system_time                                     [Tool event]

[v5]: Add missing alias check.
