[Buildroot] [PATCH 4/5] support/docker: use a fixed Debian snapshot

Sun Feb 4 14:44:25 UTC 2018


Since we're now using a specific base image tag, we need to also use a
specific, stable repository to get additional packages from for this
image.

As such, use the Debian snapshot that matches the base image.
