bitbake: cooker: Fix exit handling issues

The shutdown() call should definitely not be waiting for idle, since we
expect execution and events to continue even after setting either shutdown
state. This was causing the UI to appear to hang at Ctrl+C interrupts.

Also ensure that if we reset cooker, we stop any active parser processes
since these currently appear to be being left behind.
