openssl/ssl.h: restore some renamed public SSL_CTRL defines

Fixes #6022

In commit de4d764e3271, the following SSL_CTRL #define's where renamed

    SSL_CTRL_GET_CURVES        ->  SSL_CTRL_GET_GROUPS
    SSL_CTRL_SET_CURVES        ->  SSL_CTRL_SET_GROUPS
    SSL_CTRL_SET_CURVES_LIST   ->  SSL_CTRL_SET_GROUPS_LIST
    SSL_CTRL_GET_SHARED_CURVE  ->  SSL_CTRL_GET_SHARED_GROUP

The corresponding function-like macros (e.g, SSL_get1_curves(ctx, s)) were
renamed, too, and compatibility #define's were added. This was overlooked for
the above constants. Since the constants are part of the public interface,
they must not be removed for a minor release.

As a consequence the Qt5 configure check (and the build) fails.
