crypto_sign_init_first_pass: Swap emphasis

The original emphasis, when skimmed, made the message read that the
first pass *causes* loss of all security, which is the opposite of what
we want to emphasize.

Also bump authorship notice years while there and mdoc date that we
forgot to bump when we introduced the power-analysis and glitching
example.
