[PATCH 1/1] dpkg-prebuilt: ensure fetched packages are valid debian packages

[Felix Moessbauer <felix.moessbauer@siemens.com>]

In case of dpkg-prebuilt, we need to check if the fetched packages are
valid debian packages to only deploy valid ones into the sstate cache.
Otherwise broken packages might end up in the cache and break future
builds.
