nocturne: Change FIFO settings
Overly large sensor batches lead to timestamp synchronization issues on Nocturne, causing - among others - CTS to sometimes fail the sensor batching tests. Reduce the size of the FIFO and restore the threshold to being a third of the size. This value was changed in CL:1134494 in an attempt to solve a problem which turned out to be unrelated.
