Related: coreos#1159 I want to start converting some of the ostree/rpm-ostree tests to using kola more "natively". This is part of that; the `run-ext-bin` command injects a single binary into the target system, driving it via a systemd unit to completion. There are further elaborations of this, including injecting a full container, etc. (That is cheap in the local qemu case particularly once we have virtio-fs)
