[ostree] deploy: Do not prune repository

[Matthew Barnes <mbarnes src gnome org>]

    deploy: Do not prune repository
    
    To support deploying older commits:
    
      ostree pull <remote> <checksum>
      ostree admin deploy <checksum>
    
    Prior to this, the deploy command garbage collected <checksum> since
    there's no ref pointing to it, and then ostree_sysroot_deploy_tree()
    fails because it can't find the <checksum> commit.
