[openssl] backport fix to alert handling from openssl 0.9.8za to fix github repos

Fixes #15032 for any system using depends.  Any other system will need addressing.

The alternate is to use the patch found on the above ticket which specifies the use of SSLv3.  I don't know if that will have more or less implications.

The above patch isn't yet in 0.9.8 stable (it's prerelease), but we may wish to bump the library post-Gotham.
