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.
