Trim some more per-connection memory.

EVP_MAX_MD_SIZE is sized for the largest hash function supported, SHA-512, but
TLS never uses anything larger than SHA-384, which is plenty large enough. This
shaves 16 * 3 = 48 bytes of per-connection overhead plus an addition 16 * 7 =
112 bytes of per-handshake overhead. (Per-handshake structures are discarded
when the handshake completes, so this matters less.)
