Simplify Dnsmasq script
[Dnsmasq version >= 2.86](https://thekelleys.org.uk/dnsmasq/CHANGELOG) supports passing multiple IP addresses via the `address=` syntax now.

>Major rewrite of the DNS server and domain handling code. The change makes multiple addresses associated with a domain work address=/example.com/1.2.3.4 address=/example.com/5.6.7.8.

This allows us to simplify the script and the `.hosts` file workaround is no longer necessary.
