Drop self-provide retrofitting on v3 packages

Packages built with rpm <= 3.0.4 or so did not explicitly provide their
own name = version-release, so newer versions retrofitted that to
be able to assume it in the general operation (makes things simple as
you only need to look at provides). Since we no longer support
installing such packages, satisfying their dependencies is not relevant.
