Replaces for nvidia-kernel-dkms packages

[Russ Allbery]

The nvidia-kernel-dkms packages all Provide and Conflict with
nvidia-kernel-dkms since it only makes sense for one of them to be
installed at the same time.  Lintian noticed that they don't have a
Replaces, per Policy 7.6.2.  I think the semantics in Policy 7.6.2 are
what we want here and adding the Replaces would be correct.

Does that sound right?
