keyringctl:
Add `derive_user_from_target()` to derive the username from an existing
public key in the target directory when importing (updates to) an
already known key.
Change `convert()` to either use a custom name override (if provided), a
username derived from target dir (if existing) or the file name of the
to be imported file as username.
