You can't. The whole point of Bcc is that the sending SMTP server
removes the header before the mail is sent, so that the other recipients
can't see someone was CCed. 

Filtering on the envelope recipient address ought to be sufficient,
unless that address is getting rewritten somewhere in the mail path.

I'm not sure exactly what you're doing here, but if you're passing
sieve-test a mail that does actually have a Bcc line with your address
in, I would expect it to work. The problem is that ordinary incoming
mail won't have that line.
