Which recipient address is the one which is resulting in you getting one
of the two copies of the outbound mail?

You're after address _rewriting_, where most of Exim focuses on
redirection and delivery, so it's a little buried in the manual unless
you already know the distinction.
http://www.exim.org/exim-html-current/doc/html/spec_html/ch-address_rewriting.html
It's not clear though whether or not you want to _add_ the delivery to
the Bcc, or just add it as a header. Normally Bcc: headers are not
explicitly added.
You need to draw a distinction between the RFC5322 headers, which you
have shown, and the RFC5321 routing envelope, which is what's in use for
deciding where one particular copy of a mail is sent. By the time
you've gotten the mail, the From/To/Cc/Bcc headers are not used for
routing at all, you're only getting one of the two (or more) copies sent
out originally, and you need to decide both what should be in the
routing envelope (passed to/from SMTP as MAIL FROM and RCPT TO commands)
and the display headers (which were probably used during initial
submission to derive those routing addresses, but not thereafter).
