This attempts to fix the issue described at https://github.com/NixOS/nixpkgs/pull/22219#issuecomment-291801133. Any change to the custom packages passed to RStudio causes this to completely rebuild RStudio, which is completely unnecessary and also a bit of a hindrance as it's a fairly slow build. This rolls back most of that old PR, and instead implements something more like rWrapper. Existing configurations with the old useRPackages will break.
