protoc now generates grpc code in a separate file from protobuf code.
Also, grpc servers are now required to embed an "unimplemented"
interface from the generated .pb.go file, which provides forward
compatibility.
Update the generate.go files since the invocation for protoc has changed
with the split into .pb.org and _grpc.pb.go.
Fixes#5368
There are some changes to the code generated in the latest version, so
this modifies every .pb.go file.
Also, the way protoc-gen-go decides where to put files has changed, so
each generate.go gets the --go_opt=paths=source_relative flag to
tell protoc to continue placing output next to the input.
Remove staticcheck from build.sh; we get it via golangci-lint now.
Pass --no-document to gem install fpm; this is recommended in the fpm docs.
