Create a patch for OpenSSL to fix valgrind uninitialized value errors

[Douglas R. Reno]

While troubleshooting the cURL test suite on OpenSSL-1.1.1c, I discovered the following PR

​https://github.com/openssl/openssl/pull/8606

We need to apply the commit in this to OpenSSL.

This can be fixed by a sed:

crypto/rand/rand_lib.c

    struct {
        void * instance;
        int count;
-   } data = { NULL, 0 };
+   } data;

+   memset(&data, 0, sizeof(data));
    pool = rand_pool_new(0, min_len, max_len);
    if (pool == NULL)
        return 0;
