This is needed because the project does not have a `go.mod` file and gets sent to go 1.16 semantics whenever it's imported by another project and `any` doesn't exist in go 1.16, but the linter requires us to use `any` here. Setting the `go:build` tag forces the per-file language to the go version specified. Signed-off-by: Jonathan A. Sternberg <jonathan.sternberg@docker.com>
