scripts: Fixed typo in parameter that was causing exception
There is a typo in the logging parameters, "filname" is being used instead of "filename" for yocto-kernel, yocto-layer and wic scripts. This didn't cause issues before since python 2 didn't validate unused parameters but with python >= 3.4.3 an exception is thrown. This patch fixes this parameter name.
