Duplicate packages test failing

[contyk]

Several packages in the current package lists are listed in more than one version. This is caused by the depsolver using an older version available in the frozen set because dependencies of the overrides set cannot be satisfied, either directly or somewhere deeper in the chain.

When you then attempt to build packages, only the latest, broken version is installed and the build fails on unresolved dependencies.

The current dupes reported by the tests are (unified for all arches):

• dbus
• dbus-libs
• emacs-filesystem

The dbus dups are caused by the new cmake-filesystem dependency of the 1.11.16 version in overrides. We provide cmake-3.8.2 while cmake-filesystem was introduced in cmake-3.9.0. Updating cmake in our overrides should fix that problem.

I have yet to look into emacs.

dbus should be fixed in 6fecfca.

We still have a strange dup in devel/hp/ppc64le/selfhosting-source-packages.full.txt (only) but the rest should be fine. Let's see how problematic it will be.
