Tell ASan about the OPENSSL_malloc prefix.

OpenSSL's BN_mul function had a single-word buffer underflow (see
576129cd72ae054d246221f111aabf42b9c6d76d). We already independently
fixed this but, if we hadn't, ASan wouldn't have noticed because of
OPENSSL_malloc.

ASan has runtime hooks we can call to make it more accurate.
