Lily Ballard 4ebc22781d psc-package: Stop using haskellPackages to build
Switch to the approach taken by
https://github.com/justinwoo/easy-purescript-nix/blob/master/psc-package-simple.nix

This downloads a prebuilt release and patches the linker paths. It
reduces the number of supported platforms, but ensures we're using the
official supported psc-package compiler. The `haskellPackages` approach
wasn't supported and was leading to version conflicts with dependencies.
