openssl: define HAVE_OPENSSL_VERSION for OpenSSL 1.1.0+

openssl: define HAVE_OPENSSL_VERSION for OpenSSL 1.1.0+

Prior to this change OpenSSL_version was only detected in configure
builds. For other builds the old version parsing code was used which
would result in incorrect versioning for OpenSSL 3:

Before:

curl 7.80.0 (i386-pc-win32) libcurl/7.80.0 OpenSSL/3.0.0a zlib/1.2.11
WinIDN libssh2/1.9.0

After:

curl 7.80.0 (i386-pc-win32) libcurl/7.80.0 OpenSSL/3.0.1 zlib/1.2.11
WinIDN libssh2/1.9.0
