[PATCH] Makefile: Add NEEDS_CRYPTO_WITH_SSL

The Makefile comment for NEEDS_SSL_WITH_CRYPTO says to define it "if
you need -lcrypto with -lssl (Darwin)."  However, what it actually
does is add -lssl when you use -lcrypto and not the other way around.
However, libcrypto contains a majority of the ERR_* functions from
OpenSSL (at least on OS X) so we need it both ways.

So, add NEEDS_CRYPTO_WITH_SSL which adds -lcrypto to the OpenSSL link
flags and clarify the difference between it and NEEDS_SSL_WITH_CRYPTO.

 Compilation using BLK_SHA1 on OS X 10.5 and 10.6 (at least) is still
 broken without this patch.

 Alex Riesen [off-list ref] pointed out that just adding LIB_4_CRYPTO
 to git-imap-send is simpler, but judging from the fact that nobody else
 has complained about this issue, I'm guessing that the need for -lcrypto
 when using -lssl is not widespread.  (Or BLK_SHA1 isn't getting used much
 or those who do don't compile git-imap-send with SSL.)
