patches/RELENG_8_3: Add OpenSSL 0.9.8x backport patch (Refs #2616)

Obtained from 8-STABLE, updates system-integrated OpenSSL
version as some applications start depending on newer features
not found in the version shipping with FreeBSD 8.3

Regular FreeBSD releases starting 9.1 will contain this
bump, it's only interesting for 8.3.
