[OE-core] Backport OpenSSL 1.0.2n

[robert_joslyn at selinc.com]

I'm working with the pyro release, and noticed that it's still using 
openssl 1.0.2k. The latest version in the 1.0.2 series is 1.0.2n, which is 
already available on master. Is there a reason that the newer version 
hasn't made it back to pyro (or rocko, which is on 1.0.2m)? I know new 
package versions are not normally backported, but looking at the change 
log, I only see one change mentioned that is not a CVE fix (the 1.0.2l 
release):

I can send patches to bring 1.0.2n to rocko and pyro if they will be 
accepted.

Thanks,
