mod_ssl: follow up to r1861950: allow for OPENSSL_init_ssl() without autoconf.

For systems with no autoconf (eg. Windows), still check for and use
OPENSSL_init_ssl() based on OpenSSL version >= 1.1.0.

Usual LibreSSL gotcha, exclude LIBRESSL_VERSION_NUMBER from this new heuristic
since autoconf is likely available in this case.
