CORE-1779 Reset mnt/state/var folder permissions

Due to launchpad bug # 1374626, UIDs can change between full image
deployments as accounts are burned into the image and depending on
the elements included between images, may have differing owners.

As a result, this commit, while it does not fix the root cause, is
intended to reset the permissions so applications can start after
an upgrade.
