sepia-fog-images: Remove finished hostnames properly

Before this change, if there were 3+ hosts in $remaininghosts and one of
the hostnames in the middle finished, sed would remove the hostname and
its trailing space which would mash the last two hostnames together.

```
Example:

remaininghosts="mira071 smithi164 mira001"
remaininghosts=$(echo $remaininghosts | sed -e "s/ *smithi164 *//")
$ echo $remaininghosts
mira071mira001
```
