Summary: ldif2db replaces existing modify/create name and timestamps
https://bugzilla.redhat.com/show_bug.cgi?id=525007
[Problem Description]
LDIF that is imported might contain createTimestamp, creatorsName,
modifyTimestamp, or modifiersName. The import code since FDS 1.2 inserts
these attributes but it should only do so if they're missing; any
existing values should take precedence.
[Fix Description]
Only insert the attributes if they don't already exist in the entry.
attrlist_find() rather than slapi_entry_attr_find() is used because the
latter reports attributes with empty values as being missing attributes.
[Proposed Fix]
