bitbake: knotty: Catch exceptions on broken pipes

Browse Source 
Any exceptions that occur in calls to logging methods are automatically
suppressed, including exceptions due to broken pipes.

However, the knotty summary messages are printed directly to stdout, which
means that any broken pipes will cause an exception traceback in python.

By wrapping the summary section in a try / catch block we can check for
IOError exceptions caused by broken pipes and let them pass.
