nixos: Add sd_image_minimal_new_kernel_no_zfs 

Support for ZFS, while desirable, is problematic with newer kernel
releases. The stable ZFS release seldom supports the current newest
kernel version, and this makes the new_kernel image basically useless as
it cannot be published, and is not often built with new kernel releases.

This uses a dirty workaround to work around the fact it is impossible to
remove a list item from a modules system list type. Since ZFS support is
conditional to being supported on the current platform, we can fake ZFS
not being supported *for the no-zfs build only*. This overlay is only
added when evaluating the image, nothing else.

  # Makes `availableOn` fail for zfs, see <nixos/modules/profiles/base.nix>.

  # This is a workaround since we cannot remove the `"zfs"` string from `supportedFilesystems`.

  # The proper fix would be to make `supportedFilesystems` an attrset with true/false which we

  # could then `lib.mkForce false`
