Bug description:
[Impact]
Upgrades of linux-image-generic-hwe-16.04-edge will fail to configure because
the post-update script for zipl will fail.
[Test Case]
Upgrade linux-image-generic-hwe-16.04-edge from xenial to xenial-proposed on
s390x.
[Regression]
zipl update on s390x might fail, causing the system to be unbootable.
