tests/acceptance: Handle cpu tag on x86_cpu_model_versions tests

Some test cases on x86_cpu_model_versions.py are corner cases because they
need to pass extra options to the -cpu argument. Once the avocado_qemu
framework will set -cpu automatically, the value should be reset. This changed
those tests so to call set_vm_arg() to overwrite the -cpu value.
