buildDhallUrl: Respect proxy environment variables

Browse source 
`buildDhallUrl` is a fixed output derivation, which means
that we can (and should) inherit impure proxy-related
environment variables for fetching URLs.

The motivation for this change is:

https://discourse.dhall-lang.org/t/cant-build-a-nixified-dhall-package-in-a-sandbox-depending-on-the-environment/

… where a `buildDhallUrl` derivation was failing in a restricted
networking environment due to not inheriting proxy-related
settings.
