You should find recent versions of zsh have this in by default.

The code you show doesn't do anything special for user names.  The current
support built into the completion system adds any users stored in the
style "users", then any found by scanning the system's password database.
This doesn't appear to have changed recently.

Try setting a few user names for it to complete explicitly and see
if that works:

  zstyle ":completion:*" users arthur brenda charlie deirdre
