[PATCH b4] send: honor excluded addresses in per-patch Cc summary

When --not-me-too or b4.send-me-too=no is used, the sender's address is
added to the exclusion list and removed from the final To/Cc headers.
However, the pre-send summary prints per-patch Cc candidates without
applying the same exclusion.

This can result in output such as:

  [PATCH ...] ...
    +Cc: User <[email protected]>

even though the generated message does not actually Cc that address.

Filter the per-patch Cc summary through cleanup_email_addrs() with the
same exclusion set used by the actual send path, so that the displayed
recipients match the recipients that will be used.
