  Test EVP_PKEY_get_size for zero return

The test_rsasve_degenerate_ciphertext calls EVP_PKEY_get_size and uses
that returned value as an array index (offset by -1), but fails to check
if the returned size is greater than zero (which can be returned in an
error case), leading to an array index underflow.

Ensure that the returned value is greater than zero
