redhat: Fix RT kernel kvm subpackage requires

kernel-rt-kvm package currently depends on kernel-rt meta-package, so it fails to install if kernel-rt is not installed as well. All the other kernel-rt-* packages however only depend on the kernel-uname-r so they do not require the kernel-rt meta-package.

Layered products doesn't use kernel-rt meta-package to side load kernels, as it would bring in unwanted additional dependency. They install kernel-rt-* packages and this is then currently a problem for kernel-rt-kvm.

kernel-rt-kvm doesn't actually require kernel-rt meta-package, but only the correct kernel-rt (core) version. So, fix its dependencies accordingly.
