You can get the additional package via:
apt-get install s390-tools-cpuplugd

When it is installed, the service is enabled by default!! (OK, since it
is a sub-package)

root at s8330003:~# systemctl status cpuplugd.service

And cpu hotplugging works also as expected. Closed.

Title:
  s390: missing cpuplugd

Status in s390-tools package in Ubuntu:
  Fix Released

Bug description:
  Requirement for : cpuplugd

  This also includes a configuration file, man-page, and init script.
  The suggested package concept is a subpackage of the s390-tools.

  This is a command and a set of rules in a configuration file to dynamically
  enable or disable CPUs. For Linux on z/VM, you can also dynamically add or
  remove memory.

  Sample debdiff to integrate the cpuplugd daemon as subpackage of the
  s390-tools
