qemu: Translate feature names from query-cpu-model-expansion

Browse Source 
By default query-cpu-model-expansion only reports canonical names of all
CPU features. We do some magic and call the command twice to get all
possible spellings of the features, but being able to consume canonical
names will allow us to drop this magic.
