[U-Boot] [PATCH v3] patman: Do not Cc addresses included in To list

[Otavio Salvador]

In case an address is listed in the To list, those will be skipped on
Cc list or user might end with a duplicated message.

This fixes the case when a tag points to same address used as series
destination thus avoiding duplicated sending.

Changes in v2:
- use if 'to' in self: to remove the try block

Changes in v3:
- readd try / except block to handle the valid error
