qcow2: Make cache=writethrough default

Some block drivers perform badly with @option{cache=writethrough}, most notably, qcow2. If performance is more important than correctness, -@option{cache=writeback} should be used with qcow2. By default, if no explicit -caching is specified for a qcow2 disk image, @option{cache=writeback} will be -used.
