The generated aar for native plugin in build/host/outputs/repo should have a correct version number.

### Steps to reproduce

1. create a flutter project
2. add a plugin with native code, such as image_picker(It depens on image_picker_android)
3. build AAR for android with `flutter build aar --build-number 2.0`
4. check the output assets located in `"${projectRoot}/build/host/outputs/repo/io/flutter/plugins/imagepicker/image_picker_android_release/"`. The generated version of aar will be "2.0"(same as `--build-number` specified).
5. check the version number of `image_picker_android` in `${projectRoot}/pubspec.lock`, It might be "0.8.12+1".
6. clean the workspace with `flutter clean`(this will not remove `pubspec.lock`)
7. re-build AAR for android with `flutter build aar --build-number 3.0`
8. check the output assets again. The generated version of aar will be "3.0" this time.
9. check the version number of `image_picker_android` in `${projectRoot}/pubspec.lock`, It should still be "0.8.12+1".

### Expected results

The generated aar for image_picker_android in `"${projectRoot}/build/host/outputs/repo/io/flutter/plugins/imagepicker/image_picker_android_release/"` should retain it's version number when I rebuild aar without changeing it's version.

### Actual results

It always has the same version of `--build-number`, even though I didn't change the version number of image_picker in pubspec.yaml.

### Code sample
