[PATCH v3 5/5] ci: use snapshot in reproducible builds test

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

As we now have easy to use snapshot support, we also switch over the
reproducible builds test to use a snapshot. By that, we both test the
snapshot support, as well as make sure to always build against a common
set of packages.
