Add extra files needed for dracut (#36)

* Add extra files needed for dracut

If we are dropping cos-immutable-rootfs then we have to include the
missing files that the package already added.

For example, the several dracut configs of modules for the initramfs
stage, or the general config for the dracut file.

We also need to install and link the initramfs elemental stage service
as that its no longer provided by the cos-immutable-rootfs package and
not integrated into immucore yet
