ffserver_config: remove useless defaults

Options are already set to its defaults by AVOption API.
The only difference is for qmin, new default is 2, ffserver set to 3.
It is dead code because if condition is not meet unless user set option to 0.
Meeting condition would mean that ffserver overwrites explicity set option.
