Update protoc generation to use vendored protos
Update protoc generation to use vendored protos

Use vendored-in protos in the project path rather
than expecting developers to have them in a local
path on the host. This made a generated change
in the FileDescriptor content, but everything else
matches and binaries are building properly.
