Samuel Dionne-Riel 6638690261 ruby: Use hostPlatform

Using `stdenv.targetPlatform` gives the wrong platform in buildPackages.

E.g.:

```
 $ nix-diff --color never $(env -i nix-instantiate -A pkgs.ruby -A pkgs.pkgsCross.aarch64-multiplatform.buildPackages.ruby)
- /nix/store/w8wk99p4gadns35n2l0fr7wx56jlwnnx-ruby-2.6.6.drv:{out}
+ /nix/store/5ywj7nicjai6ji4g33yh6nvz1b5fq7xw-ruby-2.6.6.drv:{out}
• The input named `ruby-2.6.6` differs
  - /nix/store/4a6nag89dcxwdf32820z6dfwwpfgab8s-ruby-2.6.6.drv:{out}
  + /nix/store/40pakkdfv578zffx3y11qd5ckcp2xpzm-ruby-2.6.6.drv:{out}
  • The environments do not match:
      postInstall=''
          # Remove unnecessary groff reference from runtime closure, since it's big
          sed -i '/NROFF/d' $out/lib/ruby/*/*/rbconfig.rb

          # Bundler tries to create this directory
          mkdir -p $out/nix-support
          cat > $out/nix-support/setup-hook <<EOF
          addGemPath() {
            addToSearchPath GEM_PATH \$1/lib/ruby/gems/2.6.0
          }
          addRubyLibPath() {
            addToSearchPath RUBYLIB \$1/lib/ruby/site_ruby
            addToSearchPath RUBYLIB \$1/lib/ruby/site_ruby/2.6.0
            addToSearchPath RUBYLIB \$1/lib/ruby/site_ruby/2.6.0/←x86_←→aarch→64-linux
          }

          addEnvHooks "$hostOffset" addGemPath
          addEnvHooks "$hostOffset" addRubyLibPath
          EOF

          rbConfig=$(find $out/lib/ruby -name rbconfig.rb)
      ''
• Skipping environment comparison
```

`pkgs.pkgsCros.*.buildPackage.ruby` should be equivalent to `pkgs.ruby`.
It wasn't.
