This is expected behaviour.

You haven't told Postfix about /var/lib/mailman/data/aliases.  Do this 
like so?

alias_maps = hash:/etc/aliases,
   hash:/var/lib/mailman/data/aliases

and you'll probably want

virtual_alias_maps = hash:/etc/postfix/virtual,
         hash:/var/lib/mailman/data/virtual-mailman

It looks like you've done much of the rest that you need to do, as the 
alias file is in fact being updated.

In my personal experience, you may find yourself missing important steps 
when installing Mailman from packages.  It wasn't until I needed to 
install from sources that I actually read the installation instructions 
from cover to cover, and realised I'd missed a few crucial (or at least 
advisable) steps.  So you might want to read 
http://list.org/mailman-install/
