util/stack: update protoc options to work with newer versions Generating the util/stack protos failed when updating protoc-gen-go to v1.5.2; it looks like this is the only proto that's not generated using protoc-gen-gogo): util/stack/generate.go protoc-gen-go: unable to determine Go import path for "stack.proto" Please specify either: • a "go_package" option in the .proto source file, or • a "M" argument on the command line. See https://developers.google.com/protocol-buffers/docs/reference/go-generated#package for more information. --go_out: protoc-gen-go: Plugin failed with status code 1. util/stack/generate.go:3: running "protoc": exit status 1 Newer protobuf versions expect a go package to be set. Other .proto files in this repository use the bare package name, but with protoc-gen-go v1.5.2, this produces an error (package names must at least have a "/"). In addition to including the option to the .proto file also changes the generated result (`options go_package "<package name>"`). Using the `-go_opt=M<package name>` option on the other hand, didn't change the result (while still on protoc-gen-go v1.3.5), so I used that option instead. protoc-gen-go v1.5.2 also changed the behavior where the generated file is stored, seemingly relative to the `../../vendor` path specified. This coud be fixed either by setting `--go_out=../../`, which was a bit counter-intuitive, or setting the `--go_opt=paths=source_relative` option. The latter also prevented v1.5.2 from storing the file in `utils/stack/github.com/moby/buildkit/utils/stack/` (sigh).
