Fix "--debian-installer cdrom" and its interaction with binary_package-lists

apt-ftparchive is not able to differentiate between .deb and .udeb so
we have to install them in different pool directories so that we can
regenerate the Packages files without having the .udeb show up
unexpectedly.

Since binary_package-lists can overwrite the Packages files generated
in installer_debian-installer we have to ensure that it also updates
the Release file created formerly.

Ideally we should find a way to avoid the duplication of this logic.
