target-i386: Prepare "vendor" property for X86CPU
Using it now would incur converting the three x86_def_t vendor words into a string for object_property_set_str(), then back to three words in the "vendor" setter. The built-in CPU definitions use numeric preprocessor defines to initialize the three words in a charset-safe way, so do not change the fields to char[12] just to use the setter.
