disk_layout: Bump stateful partition to 4 GiB

FAFT tests are failing because there isn't enough space on the USB
stick for autotest to install itself. Between whatever autotest is
syncing down and the 600MB "catapult" directory, 3GB seems to no longer
be enough. Bump to 4, and start to consider a solution where we expand
the stateful partition during cros flash. Because really, bloat is like
entropy: one only ever gains it.
