(Re)Apply workaround for single-user sandbox perm issue (#794)

Fixes the following error that occurs on single-user nix installations when compiling an otherwise trivial cabalProject/stackProject: > error: moving build output '/nix/store/d5zpqajgysbk38iqgcjwgqx44amqh9pw-ghc-boot-src' from the sandbox to the Nix store: Permission denied Tested on ghc-8.4 where there is nothing in the cache. Materialisation of ghc(-boot-src) also still works/works again. See https://github.com/input-output-hk/haskell.nix/issues/466 and the previous attempt to fix this at https://github.com/input-output-hk/haskell.nix/pull/399 (d3905d62b5c5ca7f671f5a301c4fcab433ebf68c..8561498e7d9237cc271f9ffd7bff19e3293122b0)
