stages/ostree.fillvar: fill the correct var

Browse source 
The idea behind the stage is to provision `var` of the stateroot,
i.e. the `var` the is shared amongst all deployments for a given
os (indicated by `osname`, e.g. `fedora`, `centos`, ...).
For `systemd-tmpfiles` to infer the correct paths, it needs to be
run on the deployment. The `var` of the latter needs to be bind-
mounted to the `var` of the stateroot, because it is shared. This
was always the intention but not what the code did. Fix this by
getting the `var` of the stateroot and bind it to the `var` of
the deployment.
NB: In reality this never mattered since systemd-tmpfiles is also
run during system startup.
