[PATCH 2/3] bitbake: knotty: Treat verbconsole as a console output

[Joshua Watt <jpewhacker@gmail.com>]

The BitBake.verbconsole needs to be treated like a console output logger
(meaning that the TerminalFilter attaches an InteractConsoleLogFilter to
it), even if it's not directly attached to the root 'BitBake' logger.
First, assign a special "is_console" property to the relevant handlers,
then look for the property in the handlers from the configuration object
return by bb.msg.setLoggingConfig(). Finally, pass the list of all
handlers to the TerminalFilter object; it doesn't care about the
difference between console and errconsole, so pass all the relevant
handlers as a list.

This fixes cases where the console output was corrupted when messages
were sent to the 'BitBake.verbconsole' handler.
