fixup! Creating Dockerfile to /

[fauust]

The symlink permits do build container directly from / Same as what cjdns does (that was probably updated).

Before:

~/gh/yggdrasil-go develop
❯ podman build .
Error: no FROM statement found

After:

~/gh/yggdrasil-go dockerfile-symlink
❯ podman build .
[1/2] STEP 1/5: FROM docker.io/golang:alpine AS builder
[1/2] STEP 2/5: COPY . /src
--> 3806ec0449ca
[1/2] STEP 3/5: WORKDIR /src

I'm a bit confused about this PR, it just deletes the file that was already there and recreates it?

@neilalexander the file is not a symlink upstream, see bellow:

GitHub interface doesn't seem to show the difference though.
