core/tests: Switch to new boot.zfs.package option

When fixing evaluation for supportedFilesystems in
21fdf5e0407d11524dbc0c42743358d9b973943c, I forgot about another change
related to ZFS options, which leads to the following evaluation error:

  The option `boot.zfs.enableUnstable' can no longer be used since it's
  been removed. Instead set `boot.zfs.package = pkgs.zfs_unstable;`
