autoconf: Fix engine checks for openssl 1.1
In openssl 1.1, ENGINE_cleanup became a #define instead of a function
(because it's no longer needed as engines are self cleaning). Update
the autoconf.ac script to check for ENGINE_cleanup as a declaration to
avoid falsely undefinig HAVE_OPENSSL_ENGINE in openssl 1.1+
