crypto/engine/eng_openssl.c: define TEST_ENG_OPENSSL_RC4_P_INIT conditionally
When OpenSSL is configured with 'no-stdio', TEST_ENG_OPENSSL_RC4_P_INIT
shouldn't be defined, as that test uses stdio.
Fixes
/* #define TEST_ENG_OPENSSL_HMAC */
/* #define TEST_ENG_OPENSSL_HMAC_INIT */
/* #define TEST_ENG_OPENSSL_RC4_OTHERS */
+#ifndef OPENSSL_NO_STDIO
# define TEST_ENG_OPENSSL_RC4_P_INIT
+#endif
/* #define TEST_ENG_OPENSSL_RC4_P_CIPHER */
