BUILD.bazel: different package path for annotations pkg

Similar but different error:

```
link: package conflict error: google.golang.org/genproto/googleapis/cloud/location: package imports google.golang.org/genproto/googleapis/api/annotations
	  was compiled with: @org_golang_google_genproto//googleapis/api/annotations:annotations
	but was linked with: @org_golang_google_genproto_googleapis_api//annotations:annotations
```

Compare with the original:

```
link: package conflict error: cloud.google.com/go/pubsub/apiv1/pubsubpb: package imports google.golang.org/genproto/googleapis/api/annotations
	  was compiled with: @org_golang_google_genproto_googleapis_api//annotations:annotations
	but was linked with: @org_golang_google_genproto//googleapis/api/annotations:annotations
```
