Don't download OpenSSL from ftp.openssl.org anyomre

OpenSSL announced that they're changing how they handle releases in this
blog post: https://openssl.org/blog/blog/2024/04/30/releases-distribution-changes/

The tl;dr is that:

* ftp.openssl.org is being shut down (even for HTTP access)
* The releases at openssl.org/source will redirect to github

This commit just changes over to using openss.org/source instead of
ftp.openssl.org. We might also need to switch to downloading directly
from Github... let's see.
