tests/vm: switch centos.aarch64 to CentOS 8 Stream
Switch this test over to using a cloud image like the base CentOS8 VM test, which helps make this script a bit simpler too. Note: At time of writing, this test seems pretty flaky when run without KVM support for aarch64. Certain unit tests like migration-test, virtio-net-failover, test-hmp and qom-test seem quite prone to fail under TCG. Still, this is an improvement in that at least pure build tests are functional.
