go: empty Go package

The only purpose at the moment is to allow vendoring of the SPDK
source code into Go projects which manage dependencies with the "dep"
tool. That tool is designed for Go projects and as a sanity check
rejects any dependency which does not have at least one Go file, at
least at the moment (https://github.com/golang/dep/issues/1306).

+// spdk might one day provide Go bindings for the SPDK RPC API.
+// At the moment all that it does is allowing a Go project
+// to vendor in the SPDK source code via dep with this
+// in Gopkg.toml:
+//
+// required = ["github.com/spdk/spdk/go"]
+//
+// [prune]
+//  go-tests = true
+//  unused-packages = true
+//
+//  [[prune.project]]
+//    name = "github.com/spdk/spdk"
+//    go-tests = false
+//    unused-packages = false
