Subject: [PATCH 27/48] BE: search with sysdb_search_with_ts_attr

Previously, the background refresh code had used sysdb_search_entry()
which does not run the search on the timestamp cache. Instead, this
patch changes to using sysdb_search_with_ts_attr with the
SYSDB_SEARCH_WITH_TS_ONLY_TS_FILTER optimization because currently only
the dataExpireTimestamp attribute is included in the filter.
