futhark: init at 0.6.2

multi-ghc-travis has been renamed to haskell-ci which is now also on Hackage.

We had a few "overrides" in configuration-common.nix that were really
extensions. They introduced packages that weren't in hackage-packages.nix.

The advantage of having a dedicated file for these packages is that we can still
place Nix-specific overrides to these packages in configuration-nix.nix. We
weren't able do this before because configuration-nix.nix extended only the
packages from hackage-packages.nix.

The fact that futhark is a Haskell package is an implementation detail. To
install it users should just have to specify `futhark` instead of
`haskellPackages.futhark`.

Additionally futhark is overridden with `haskell.lib.justStaticExecutables` to
reduce closure size.
