unfortunately, this approach doesn't work with "bitbake package-index", which
calls generate_index_files() in package_manager.py. That's why I implemented
a quite ugly solution covering all cases:

Subject: [PATCH] package_manager/deb: apt-ftparchive needs a valid config

Without a valid config, apt-ftparchive aborts. Since apt-ftparchive
defaults to /etc/apt if APT_CONFIG is unset, this is only an issue
non non-Debian build hosts.
