skopeo stage: remove overlay/backingFsBlockDev file after install

Browse source 
Each time the overlay backend runs on an xfs fs it creates the
file "overlay/backingFsBlockDev" in the containers storage directory.

It is not needed in the image as skopeo recreates it each boot, and
since it is a block device its existance means we can't store the
resulting tree in ostree. Lets just get rid of it.
