Title:
zfsutils-linux fails to install if `modprobe zfs` fails

Fix Released
Status in zfs-linux source package in Groovy:
Fix Released
Bug description:
== SRU Justification, Focal ==
Justification: Installing zfsutils with zfs modules not available
causes the package to installation to fail. The package should install
cleanly rather than break.
== Test Case ==
# Prevent module loading
$ sudo sysctl kernel.modules_disabled=1
# Install the package
$ sudo apt install -y zfsutils-linux
This should succeed. Without the fix this fails. (See below for the
failure message). With the fix modules don't install but the package
install succeeds.
== Regression Potential ==
There may be users who expect the package to fail to install when the
zfs utils fail to install when the modules are not available. However,
this is a corner case where users are expecting broken behaviour to
occur and should not be relying on this.
The changes to the systemd rules are already in Ubuntu groovy and have
been tested, so I believe the regression potential is limited.

Description:
When installing zfsutils-linux, failure to `modprobe zfs` cause the package
installation to fail.
Ideally, modprobe should be attempted but not fatal.
Steps to reproduce:
# Prevent module loading
$ sudo sysctl kernel.modules_disabled=1
# Install the package
$ sudo apt install -y zfsutils-linux
This should succeed but fails with:
