lib/oe/utils: Improve multiprocess_lauch exception handling

Browse Source 
We've seen a cryptic:

"ERROR: Fatal errors occurred in subprocesses, tracebacks printed above"

message from oe-selftest with no other traceback information. Improve the
traceback logging to try and give a better indication of any errors that is
ocurring.
