Sebastiaan van Stijn f3ddace468 Use tempdir instead of working directory as build-context ...

The `makefile()` utility was used to create a temporary Dockerfile, and after
tests completed, this file was deleted.

However, the _build_ used the current path (`/usr/local/bin/docker`) as
build-context. As a result, roughtly 20 MB was sent as build-context for each
build, but none of the builds actually required a build-context.

This patch;

- creates a temp-dir for the test, which can be used as build-context
- changes the `makefile()` utility and removes the `cleanup` functionality
- instead, the `temp-dir` is removed after the test finishes (which also removes the temporary `Dockerfile`)
