v86/tools/docker/alpine

You can build a Alpine Linux 9p image using Docker:

1. As needed, kernel flavor (virt is smaller than lts, but don't have networking) and set of additional packages (community repo is enabled by default) can be edited in Dockerfile
2. Check and run ./build.sh with started dockerd (podman works)
3. Run local webserver (e.g. make run) and open examples/alpine.html
4. (optional) Run ./build-state.js and add initial_state: { url: "../images/alpine-state.bin" } to alpine.html
