openssl: prevent ABI break from earlier fido releases

The backported upgrade to 1.0.2h included an updated GNU LD
version-script which results in an ABI change. In order to try and
respect ABI for existing binaries built against fido this commit
partially reverts the version-script to maintain the existing ABI
and instead only add the new symbols required by 1.0.2h.
