configure: Miscellaneous minor changes to config file handling

- Move generating config.fate to a more sensible place.
- Move printing warnings to a more appropriate place.
- Improve "generated by" comment in libavutil/avconfig.h.
- Drop pointless informative output about generating config files.
- Write a standard comment header to config.asm as well.
