Deploy topology.conf unconditionally

srun will fail if slurm.conf defines use of a topology plugin
but topology.conf does not exist on login nodes. Previously,
topology.conf was only deployed to slurmd and slurmctld nodes.

```
$ srun -c 1 -n 1 --mem 1g --pty bash
srun: error: s_p_parse_file: cannot stat file /etc/slurm/topology.conf: No such file or directory, retrying in 1sec up to 60sec
srun: fatal: something wrong with opening/reading /etc/slurm/topology.conf: No such file or directory
```

This change removes the conditional and deploys topology.conf to all
nodes.

Fixes #52
