If/when grpc/grpc-go#5684 is resolved, then a program that tries to link in both that reflection package and this repo's grpcreflect package will run into problems: both would try to register the same file descriptors and types in the protobuf runtime's global registry. That would lead to a panic during program init.

So this hacks the internal packages used for the v1 service to avoid such a conflict. It also updates the script that generates code to use a longer path that is much less likely to collide with a user's files.
