Since both were functions already their place seems more appropriate in
functions.zsh. This also fixes the completion of both, since they did
not complete files before.
Other changes in `unbkp`:
- Use `mv` instead of `cp`
- Fix little typo (forgotten quote) and support specifying the
original name instead of only the backup.
- Do not "rename" the file if there is no change in name
(Leading to the prompt if the file should be overwritten)
