swift-ring-builder: exit ERROR (2) on uncaught exceptions
swift-ring-builder has three exit statuses: 0 (OK), 1 (WARNING), 2 (ERROR). Uncaught exceptions in python result in an exit code of 1, so for example problems writing a builder file to disk will result in an exit of 1 (warning) rather than 2 (error). This addresses that by overriding sys.excepthook to produce the usual backtrace and then exit 2 (error); excepthook is called when an exception is unhandled, unless that is SystemExit.
