Log Message:
openssl: Use consistent socket interfaces on SunOS.

The OpenSSL codebase is a forest of preprocessor usage so it's hard to say
exactly what's going wrong, but there's definitely inconsistent use across
the codebase, resulting in socket failures when trying to use QUIC.

Ensure recvmsg/CMSG_* interfaces are available, fixing test suite as well
as some real world regressions (e.g. devel/py-poetry) noticed by users.
