So filter out everything that is irrelevant to us. (Ideally, this would be a generalized function in common.filters that takes a list of things to keep, but that would require implementing an anti-bitmap filter, which would be hard, and which we do not need here. So that is why this function is just a local hack.) This lets 291 pass with qcow2 options like refcount_bits or data_file again.
