Update rootfs and data partitions size.

This is needed as the full image with Node-RED would consume 100% data
and would make the update command fail.

Unfortunately this means that it is not possible to upgrade from 3.4.0
to 3.5.0 without re-flashing the SD Card as the partition-layout has
changed.
