base-files: sysupgrade: rename add_*files() functions

Usage of word "add" was somehow misleading in those functions:
1. They don't really add (as in: append) anything. Result files are
   created from scratch.
2. It wasn't clear what adding files means. It could be understood as
   adding actual files somewhere (to existing archive?).

Also the word "add" was also a bit ambiguous.
