You can move the relevant parts from the site.zcml definition in
buildout.cfg to a 'principals.zcml' file (don't forget to include the
namespace declarations) and include the new file in your buildout.cfg
inside the site.zcml definition like

 <include file="../../principals.zcml" />

(Adjust the path to where the principals.zcml file is stored relative to
the parts/app folder).
