openssl: security bump to version 1.0.2e

Fixes:
CVE-2015-3193 - BN_mod_exp may produce incorrect results on x86_64
CVE-2015-3194 - Certificate verify crash with missing PSS parameter
CVE-2015-3195 - X509_ATTRIBUTE memory leak

Enable IDEA as well since otherwise the build breaks (always great
upstream) - it's no longer patent encumbered.
