vdi: Use a literal number of bytes for DEFAULT_CLUSTER_SIZE

If an expression is used to define DEFAULT_CLUSTER_SIZE, when compiled, it will be embedded as a literal expression in the binary (as the default value) because it is stringified to mark the size of the default value. Now this is fixed by using a defined number to define this value.
