bump remote api to 1.12 & add --force-rm to build

This adds a `--force-rm` flag to docker build which makes the Docker
daemon clean up all containers, even when the build has failed.

This new flag requires that we bump the remote API, so we also bump the
remote API version.

Add new consolidated mkimage scripts

These new scripts are streamlined such that, for example, "contrib/mkimage/debootstrap" is _only_ responsible for filling a directory with the results of running debootstrap, and it can accept any arbitrary arguments.
