Makefile: added OpenSSL's libcrypto to the JNI_PATH which becomes the LD...

..._LIBRARY_PATH

It was failing for me like this:

➜ scapi-memcpy git:(memcpy) ✗>./install/scapi/bin/scapi DlogExample
Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/scapi-memcpy/install/scapi/libOpenSSLJavaInterface.so: libcrypto.so.1.1.0: cannot open shared object file: No such file or directory

After added the path of libcrypto to the LD_LIBRARY_PATH, it worked better.
