ZFS includes (since 2.0.0) a pam-module, which takes the login
credentials of an user to unlock their home-dataset.
Enabling it in its current state can cause some side-effects like
prompting for a password when running `su` as root (see [0]).
Our update to ZFS 2.0.0 shipped the pam config in zfsutils-linux,
whereas debian-upstream split it out into its own optional package
This commit adopts this change.
based on debian-upstream [1] commit

The issue becomes apparent by installing the current zfsutils-linux
package and running `pam-auth-update --package` (e.g. by installing
an upgraded libpam-runtime package).
