Merge df031be628 into 7b51e23aa0

By default this Dockerfile is suitable for using dockerhub auto build
feature to build new :latest when ever there's a new push to the
github master branch allowing for simple "official" image
distribution.

Adding build args allow specifying alternate repository (default:
https://github.com/xmrig/xmrig.git) or build reference (default:
master) example:

docker build --build-arg repo=https://github.com/<username>/xmrig.git \
             --build-arg ref=dev --tag xmrig:dev .

A multi stage build is used to keep run time image small.
