futhark: introduce the top-level futhark attribute

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.
