    lib/oe/utils: Improve multiprocess_lauch exception handling
    
    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.
