Upgrade to use alpine linux 4+?

So that users can use su-exec

Major upgrade of Alpine will not happen before the next major version of Node to prevent breaking changes. You can read more about that in this issue #298

sorry that i've confused this - it is preset in 3.4+, not 4+, and user docker should use apk add --no-cache 'su-exec>=0.2'. Will close this. Thanks.
