dockerfile: Keep track of buildtime metadata
This commit build each images with the following arguments:

* IMAGE: Name of the image (e.g dockcross/base, dockcross/manylinux-x64, ...)
* VCS_REF: dockcross/dockcross commit from which this image is built
* VCS_URL: this repository obtained reading remote.origin.url
* BUILD_DATE: Date and time when the build was initiated

Then, within the Dockerfile, the metadata are associated with the image
using the "LABEL" instruction.
See https://docs.docker.com/engine/reference/builder/#/label

The corresponding labels can be found here:
http://label-schema.org/rc1/#build-time-labels

See #28
