Revert Dnsmasq script breaking change

In https://github.com/uklans/cache-domains/pull/174 the output changed
from a single `lancache.conf` to many variously named `.conf` files.
Previously, It was only necessary to configure Dnsmasq with a single
`lancache.conf` as the (also generated) `.hosts` files were referenced
within. Since said pull request it is now necessary to configure Dnsmasq
with N `.conf` files.

This commit reverts this to only needing a single `lancache.conf` file.

I also can't see anything that the multiple `.conf` files afford us.
I could see it providing an additional way of selectively disabling the
caching of domain groups. But I'd argue that using the,
`"cache_domains": { "steam": "disabled" }` way, or not having a
`default` entry is still a better way. And was previously the only way
for disabling wildcard domain groups.
