Resolves: bug 224672

Bug Description: Get rid of key/cert db prefix
Reviewed by: nhosoi (Thanks!)
Fix Description: Now that we have everything in its own instance
specific directory, we do not need the troublesome key/cert database
prefix.  This simplifies the slapd_nss_init code a great deal.
Platforms tested: RHEL4
Flag Day: no
Doc impact: YES - A couple of the pages on the wiki talk about slapd-instance-cert8.db and so on - these pages will have to change once FDS 1.1 is released
