abort in configure when only openssl-1.1.x found

We don't support openssl-1.1.x yet (see multiple threads on the
openssh-unix-dev@ mailing list for the reason), but previously
./configure would accept it and the compilation would subsequently
fail. This makes ./configure display an explicit error message and
abort.
