pfPorts/openssl: Sync w. upstream ports r311178, really fixes PADLOCK

Sync with FreeBSD ports, (likely) notable for us:
 - enables optimized NIST ECC on 64-bit
   little-endian machines (r311178)
 - fixes PADLOCK support (r311452)

While we had an interim fix for working PADLOCK support, it would
we would have had to manually re-fix stuff or o a local fix on regular
basis.

The problem was reported upstream, and completes our local interim
fix for PADLOCK support in a hopefully more durable way also for
native FreeBSD consumers. (PR 175622, thanks dinoex@)
