Work around a bug on aarch64[1] where `qemu-img` would hang about a third of the time when converting images. To be able to activate the work-around based on the environment, i.e. only on certain distributions, introduce an environment variable, `OSBUILD_QEMU_IMG_COROUTINES`, that is set in the runner and then picked up in the assembler.
