Revert lots of Cryptlib updates.
OpenSSL changes quite a bit of the key validation, and most of the keys
I can find in the wild aren't marked as trusted by the new checker.
Intel noticed this too: https://github.com/vathpela/edk2/commit/f536d7c3ed
but instead of fixing the compatibility error, they switched their test
data to match the bug.
So that's pretty broken.
For now, I'm reverting OpenSSL 1.1.0e, because we need those certs in
the wild to work.
