SparseLoopbackDisk: fix sparse file creation
The SparseLoopbackDisk class created sparse file a bit incorrecly.
First of all, it created a sparse file of wrong size - one byte more than
asked. Indeed, look at Tizen images, they are of size '2717908993', which is
2.5GiB + 1 byte.
Second of all, the file was not as sparse as it could be - because of the write
to the end, the last block was mapped.
Change this to just use 'ftruncate()' to the right size, which does the trick.
