[OE-core] [PATCH] package_deb: DpkgIndexer use apt-ftparchive that needs a valid config

[Aníbal Limón]

From: Andreas Oberritter <obi at opendreambox.org>

Since we have support of log checking in deb/ipk [1] rootfs generation
in non Debian-based hosts fails because apt-ftparchive generates a
Warning when not find /etc/apt/apt.conf.d/ (available in Debian-based
hosts).

package_manager.py: DpkgPMIndexer add support for generate and export apt
configuration.
