We can't really use `dlopen()` from a statically built binary, so let's disable this functionality if `static_build` tag is used (which is sort of a de-facto standard way of doing it). This eliminates the following warning: 🇩 bin/containerd # github.com/containerd/containerd/cmd/containerd /tmp/go-link-509179974/000004.o: In function `pluginOpen': /usr/local/go/src/plugin/plugin_dlopen.go:19: warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking [v2: add static build instructions to BUILDING.md] Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
