  Dockerfile for building a Slackware image with essential build tools

I've made this change to reduce a few layers. I kind of forgot about that method, because when I tried (when I first started learning docker) to do it using semicolons instead of ampersands, I had the problem where the build would complete and docker returned 0 even if some of the commands between semicolons would fail (I just made a PR to have that changed in the Docker docs).
