[PRQ#50936] Deletion Request for ssf-git

MarsSeed [1] filed a deletion request for ssf-git [2]: Insecure, discontinued network tunneling utility from 2018 (not maintained since that year). [a] Relies on EOL, insecure openssl 1.0. This should now be deleted from AUR. Users can find secure, reliable, maintained alternatives nowadays.
