LibreSSL defines OPENSSL_VERSION_NUMBER = 2.0, but is not compatible with
all of the latest OpenSSL 1.1 API.
Address this by defining MODSSL_USE_OPENSSL_PRE_1_1_API which is true for
anything but OpenSSL >= 1.1 (for now).

Transparency (RFC 6962) for httpd.
mod_ssl_ct requires OpenSSL 1.0.2 (in beta) and must be explicitly
enabled via configure.
Note that support/ctauditscts is purposefully not installed; it
does not properly function due to a dependency on a
certificate-transparency open source project tool which itself is
not sufficiently complete at this time.
