aa-notify: Stop aa-notify from exit after 100s of polling

Browse Source 
When run with the -p flag, aa-notify works fine for 100 seconds and then it exits.
I suspect that the issue arises from the following check on line 259 in utils/aa-notify
if debug_logger.debug_level <= 10 and int(time.time()) - start_time > 100:
    debug_logger.debug('Debug mode detected: aborting notification emitter after 100 seconds.')
    sys.exit(0)
together with line 301 in utils/apparmor/common.py which initializes debug_logger.debug_level to logging.DEBUG which has the numerical value 10.
A simple solution might be to just remove the check as I'm not quit sure why one would want aa-notify to exit when run in debug mode in the first place.
Alternatively, one could check against debug_logger.debugging (initialized to False) or change the initialization of debug_logger.debug_level to something else, but I don't know how that would affect other consumers of utils/apparmor/common.py.

For now just add dbugger_logger.debugging as an additional check as the
reason for timing out after 100s during debugging are unclear.
