Daniel Gustafsson 8d67c61c47 curldown: Fix email address in Copyright

The curldown conversion accidentally replaced daniel@haxx.se with
just daniel.se.  This reverts back to the proper email address in
the curldown docs as well as in a few other stray places where it
was incorrect (while unrelated to curldown).

Reviewed-by: Daniel Stenberg <daniel@haxx.se>
Closes: #12997
