openssl: fix incorrect return value check of RAND_* functions
* ext/openssl/ossl_rand.c (ossl_rand_egd, ossl_rand_egd_bytes):
RAND_egd{_bytes,}() return -1 on failure, not 0.
Patch by cremno phobia <cremno@mail.ru>
[ruby-core:63795] [Bug #10053]
(ossl_pseudo_bytes): Similar, RAND_pseudo_bytes() may return 0 or
-1 on failure.
