Workaround DNS issue with qemu-user-static on alpine by using Debian in the first stage #2710

Browse Source 
DNS lookups fail in qemu-user when it is built on Alpine: https://bugs.alpinelinux.org/issues/8131

Until this is resolved, we fetch the binaries from Debian and use those instead. The final stage
of the Dockerfile is still based on scratch.

We can revert this once the Alpine issue is fixed.
