REVISION SUMMARY
  As per other discussions, kdeinit has limited gains and is not widely
  deployed in KDE application. KInit as a framework is on its way out.
  
  As such using klauncher to restart a crashed application has no benefit,
  we can drop it and simplify the code significantly.
  
  It also means restarted apps stay within any namespaces set up by the launcher.

TEST PLAN
  killall -SEGV on plasmashell and dolphin
  Both restarted as expected
  The direct code path already existed, so should be safe to use

REPOSITORY
  R285 KCrash

BRANCH
  master
