Historically, KVM was available only for x86 and s390, and was invoked
via a binary called 'kvm' or 'qemu-kvm'. For a while, we've shipped a
package that was making it possible to invoke QEMU like that, but only
for these two arches. This, however, created a lot of confusion and
dependencies issues.
Fix them by creating a symlink from 'qemu-kvm' to the proper binary on
all arches and by making the main QEMU package Providing and Obsoleting
(also on all arches) the old qemu-kvm one.
