nixos/dnscrypt-proxy: remove the resolverList option

This option was initially added to make it easier to use an
up-to-date list, but now that we always use an up-to-date list
from upstream, there's no point to the option.

From now on, you can either use a resolver listed by dnscrypt
upstream or a custom resolver.
