[PATCH v6 07/13] deb-dl-dir: Fix skipping of removed files

[Vijai Kumar K <Vijaikumar_Kanagarajan@mentor.com>]

Some packages are installed and then removed, like localepurge from
image-locales-extension.bbclass. Those information would not be
available in dpkg status file. Use dpkg log instead to see if the
package has been used on the target.
