Update the stateful partition during an update test.
For test images, we may need to update the stateful partition during
a test as Y may not be compatible with X. For example, we just got
burned with the Python2.6->Python2.7 upgrade where the new rootfs
symlinked /usr/bin/python to /usr/local/bin/python2.7 which doesn't
exist unless you update the stateful partition as well.
As part of this, I have exposed the stateful update from autoupdater
to make it easier to use. I have also added unittests for this method.
