openssl: use upstream fix for CVE-2014-0198

This replaces the fix for CVE-2014-0198 with one borrowed from Fedora,
which is the same as the patch which was actually applied upstream for
the issue, i.e.:

https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=b107586c0c3447ea22dba8698ebbcd81bb29d48c
