Silence the filelock logger

[wRAR]

After we started using tldextract we sometimes get log messages from filelock with the DEBUG level, it makes sense to silence them like we do for some other libraries in

scrapy/scrapy/utils/log.py

Lines 45 to 59 in fe60c12

	DEFAULT_LOGGING = {
	'version': 1,
	'disable_existing_loggers': False,
	'loggers': {
	'hpack': {
	'level': 'ERROR',
	},
	'scrapy': {
	'level': 'DEBUG',
	},
	'twisted': {
	'level': 'ERROR',
