prog: remove target.StringDictionary

The linux string dictionary comes from extremely old times
when we did not have proper descriptions for almost anything,
and the dictionary was a quick hack to guess at least some
special strings.
Now we have way better descriptions and the dictionary
become both unnecessary and probably even harmful.
