Fix Shellcheck warnings #2

This removes most of shellcheck's warnings. It is not strictly necessary, but double quoting variable expansions is usually good practice.

Thanks for merging this. A side-effect I hadn't noticed is that it fixes custom DNS settings when the DNS variable contains multiple space-separated IPs.
