The switchNetns function was only defined for linux (dialer_netns.go, build tag linux && !android) and android (dialer_android.go, stub). This left darwin, freebsd, openbsd, windows, and other platforms with an undefined symbol at dialer.go:55. Add no-op stubs to all remaining platform files so the dialer package compiles on every GOOS.
