1. t: Make process handling more robust with IPC::Run …

   Whenever processes are spawned they need to be tracked properly for
   cleanup. This posed problems of sometimes leaking orphans when tests are
   aborted or crashed. As we already use IPC::Run we can use the same for
   other cases where we spawn processes with fork by using IPC::Run::start
   instead. Additional benefits are that we can debug the process handling
   and IPC going with https://metacpan.org/pod/IPC::Run#Debugging-Tip as
   well as be able to catch output of the processes.
   
   One example of a recent problem that should be fixed by this is
   t/05-scheduler-full.t failing to stop completely when individual test
   steps fail. This prevents the RETRY on the level of tools/retry and the
   Makefile to work as the former test never completely finishes and is
   stuck until the CI aborts the complete test run without further retries.
