Philipp von Weitershausen 1f2027a1fe Android: allow app/build.gradle to specify additional packager arguments
Summary:
If for instance you're using a custom transformer, having this hook will let you specify it without forking all of react.gradle

**Test plan:** Specified some additional packager args in my app's `android/app/build.gradle`:
```groovy
project.ext.react = [
  bundleInDebug: true,
  extraPackagerArgs: ["--transformer", "path/to/my/transformer.js"]
]
```
and ensured they show up when gradle invokes the bundler.
