ldb-tdb: Introduce a flag on ltdb_add_internal to indicate whether unique value test should be performed or not

The function ltdb_add_internal is called either from ltdb_add or
ltdb_rename. In case of add we enforce the unique test (unless it has
been relaxed by a upper module through the
LDB_FLAG_INTERNAL_DISABLE_SINGLE_VALUE_CHECK flag), but for rename as it
is translated by a delete + a add we relax the test as we can have one
or more attribute which are supposed to be single valued but that are
not (ie. when we have a couple of deleted value on a single valued
attribute), we have already done the tests on insert so make the
assumption that the values are OK.

Without this patch deleting a subnet that has been affected to more than
one site fails as the delete is in fact a rename to GUID\0DEL ... with
an attribute siteObject that has 1 active link value and 1 inactive link
value
