A solver testcase contains an abstract of all installed and available packages
(names, versions and dependencies). With this we are able to replay arbitrary
solver jobs to investigate dependency issues. For purge-kernels we need to see
which kernels and kernel related packages are installed. But also whether other
installed packages (or locks) somehow depend on an installed kernel and would
break if it gets deleted.
