Patch to allow build in MD5 support

[Chris Smith <csmith@platform.com>]

When compiling slapd with MD5 support, I could not finish the link
since some MD5 function symbols were undefined. I tracked it down to
bind.c in slapd/back-ldbm using the function calls MD5Init, MD5Update, 
and MD5Final, rather than the ldap_MD5Init, ldap_MD5Update, and
ldap_MD5Final defined in md5.c in libraries/liblutil.


Here is the patch:
