[Mac] Chromium builds shouldn't ask for access to Chrome's own secure data.

The message that this presents is:

Chromium wants to use your confidential information stored in “Chrome Safe
Storage” in your keychain. Do you want to allow access to this item?

Chromium shouldn't ask for access to Google Chrome's data, it should have its
own Chromium Safe Storage item in the keychain.
