donate-cpu.py: treat signal 6 (SIGABRT) as crash as well so we get a … (#1995) 

* donate-cpu.py: treat signal 6 (SIGABRT) as crash as well so we get a stack trace in the result

* donate-cpu.py: simplified returncode/signal check / also generate stack traces for SIGILL, SIGFPE, SIGBUS

* donate-cpu.py: avoid usage of "not" in if

* donate-cpu.py: do not overwrite returncode in crash handling
