i386: Make unversioned CPU models be aliases
This will make unversioned CPU models behavior depend on the
machine type:
* "pc-*-4.0" and older will not report them as aliases.
This is done to keep compatibility with older QEMU versions
after management software starts translating aliases.
* "pc-*-4.1" will translate unversioned CPU models to -v1.
This is done to keep compatibility with existing management
software, that still relies on CPU model runnability promises.
* "none" will translate unversioned CPU models to their latest
version. This is planned become the default in future machine
types (probably in pc-*-4.3).
