  1. Use ARG instead of ENV for temporary variables 

    We only need those temporary variables for the container build and for
the LABELS. We do not want to set those specific environment variables
for the container environment itself.

Using ARG instead of ENV lets us do that.

The ARG directive only support one value per line thus psplit the
definition into multiple ones.

See: containers/toolbox#188
See: https://docs.docker.com/engine/reference/builder/#arg
