Changelog: Always create symlinks from `/var/lib/mender-configure` to
`/data/mender-configure`. They always need to installed in a
rootfs-image prepared image, even if the software isn't, because if
the package is installed later, the links must be present or it will
act as if it is a non-rootfs image, and store the settings on the
rootfs partition, when they should be stored on the data partition.
