ziomon: Packaging needs to handle blktrace dependency

[John George]

$ lsb_release -rd
Description: Ubuntu 16.04 LTS
Release: 16.04

$ apt-cache policy s390-tools
s390-tools:
  Installed: 1.34.0-0ubuntu8.1
  Candidate: 1.34.0-0ubuntu8.1

Packaging needs to handle the installation of dependencies.

The unexpected output is shown here:
    ubuntu@s5lp1-gen01:~$ ziomon --version
    ziomon: Could not find blktrace. Please make sure that the blktrace package is installed and matches the level in the documentation.

It is a suggests, we can split this tool into a separate package.

but i guess the real bug here, is that these extra utils should not be required to display help and/or version.

we have patched other ibm utils packages to suggest installing optional components.

The issue still exists in 18.10.

https://github.com/ibm-s390-tools/s390-tools/#build-and-runtime-requirements-for-specific-tools states the package requirements. Don't remember how it's currently packaged, but if you fear too many dependencies in case of one package containing all our tools, then, yes, a subpackage for ziomon would be an option.

It's not worth the effort modifying the behavior of the --version (or --help) option due to high regression risk and real users rely on the tool working.
