On future backends with possibly bigger minimum batch sizes this subtest will fail as buffer objects may overlap. To avoid object overlapping, offsets need to be calculated with actual minimum batch size in mind. Replace hardcoded constants corresponding to the assumed 4kB minimum batch size with values calculated from a variable supposed to represent actual batch size. For now, the variable is still initialized with the 4kB value, suitable for backends currently supported by IGT.
