Bug Description

1.
$ lsb_release -rd
Description: Ubuntu 16.04.3 LTS
Release: 16.04

2.
$ apt-cache policy zfsutils-linux
zfsutils-linux:
  Installed: 0.6.5.6-0ubuntu18
  Candidate: 0.6.5.6-0ubuntu18
  Version table:
 *** 0.6.5.6-0ubuntu18 500

3. apt install zfsutils-linux does not install dkms,spl-dkms and dependencies since 16.04 kernel already contains zfs.ko

4. apt install zfsutils-linux installs all of the following:

dkms fakeroot gcc gcc-5 libasan2 libatomic1 libc-dev-bin libc6-dev libcc1-0 libcilkrts5 libfakeroot libfreetype6 libgcc-5-dev libgomp1 libitm1
  liblsan0 libmpx0 libquadmath0 libtsan0 libubsan0 linux-libc-dev manpages-dev spl spl-dkms

and then any kernel install/update then attempts to dkms rebuild zfs and spl even though the modules are already provided.

% dpkg -S /lib/modules/4.13.0-19-generic/kernel/zfs/zfs/zfs.ko
linux-image-4.13.0-19-generic: /lib/modules/4.13.0-19-generic/kernel/zfs/zfs/zfs.ko
% dpkg -S /lib/modules/4.13.0-19-generic/kernel/zfs/spl/spl.ko
linux-image-4.13.0-19-generic: /lib/modules/4.13.0-19-generic/kernel/zfs/spl/spl.ko

We can see from the package requirements, that it Recommends zfs-dkms, but only on Xenial. Releases newer than Xenial do not have this package requirement.
