Change how we calculate system size.
As per storage discussions, the best way to calculate storage for the
System is to just take all known data and subtract it from the used
bytes. There is more to the system than just the /system partition and,
even if we ignore the partitions and use the underlying block device
method of calculating it, we run into the problem of it not adding up to
the actual device size.
