Add curl package on ARM Dockerfile

[sadmin91]

On issue #308, curl package has been added on standard Dockerfile. is it possible to add this package on ARM Dockerfile?

That's not that easy because we need some kind of emulation on travis-ci to install packages while building the arm docker image. I'll see what I can do.
