bitbake: lib/bb/codeparser: ensure BufferedLogger respects target logging level

BufferedLogger was sending log records to the target logger without
checking if the logger is enabled for the level of the record - and
handle() doesn't check this either (it's normally checked earlier when
the relevant log function is called e.g. logger.debug()), leading for
example to debug messages from codeparser getting printed when the log
level for the main BitBake logger was set to logging.WARNING.
