While preparing a PR for updating nixio I discovered that the tarball ships the infamous Lenna test image, which is copyrighted material that cannot be shipped.

As we learned in #548 the image needs to be stripped from the tarball. While trivial to do, it needs to be done with every new release, unless upstream removes the image from the tarball and uses some other, non-copyrighted image for testing. As long as upstream ships the image, we cannot use update automation of any kind.

Alternatively, we could decide to retire nixio from Fedora. It's only required for a single test in elephant. That test also needs network and is thus not executed during normal build. The impact of retiring nixio from Fedora is therefore very low.
