On a number of different scenarios, such as when choosing a QEMU binary to be used on tests (or a image to use to boot a test VM), it's useful to define the architecture that should be used. This introduces both a test parameter and a test instance attribute, that will contain such a value. The selection of the default QEMU binary, if one is not given explicitly, has also been changed to look at the arch attribute.
