Makefile: T8294: autodetect CPU architecture for smoketests

We currently have hardcoded values for amd64 in our Makefile.

When calling the smoketests helpers like:
* make testc
* make qemu-live
* make test-interfaces

All expect an amd64 ISO file - if building and arm64 ISO image on an arm64
system, all those helpers do not work as it is hardcoded to amd64.
