Summary:
## Changes
All `rn_library(codegen_modules = True)` must now also specify native_module_android_package_name, like so:
```
rn_library(
name = "FBAuth"
codegen_modules = True,
native_module_spec_name = "Foo",
native_module_android_package_name = "com.facebook.fbreact.specs",
)
```
This will generate the FBAuth Java spec files under the appropriate directory: "com/facebook/fbreact/specs". It will also make the code-generated specs have the appropriate package name: "com.facebook.fbreact.specs".
