Yi Li 0e7aa6bf9e CryptoPkg: Fix pem heap-buffer-overflow due to BIO_snprintf() 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4075

Fake BIO_snprintf() does not actually print anything to buf,
it should return -1 as error.
0 will be considered a correct return value, the consumer may think that
the buf is valid and parse the buffer.
please refer to bugzilla link for details.
