test-runner: fix process cleanup

Browse Source 
Processes which were not explicitly killed ended up staying around
forever because they internally held references to other objects
such as GLib IO watches or write FDs.

This shuffles some code so these objects get cleaned up both when
explititly killed and after being waited for.
