bitbake: msg: Ensure manually created loggers have the once filter

Loggers created with a logging configuration file automatically get the
once filter applied to ensure that warnonce()/erroronce() only appear a
single time. The same filter needs to also be added to
bb.msg.logger_create() to ensure that manually created loggers have the
same behavior
