omen/*: check kernel version through config instead of pkgs

The previous implementation was checking the kernel version through
`pkgs.linux`, which is only representative of the final system if
`boot.kernelPackages` is left as the default value of
`pkgs.linuxPackages`.

You can of course change this to other package sets, such as
`pkgs.linuxPackages_latest`. Instead, we now reference the kernel
through `config.boot.kernelPackages.kernel`.
