Remove long-dead LogsExportCursor and PersistedRangeLong

LogsExportCursor was only used by ExportLogsTaskServlet, which we removed a long time ago.  It's just dead code.  The PersistedRangeLong type was only written for use by LogsExportCursor, and since it hasn't picked up new users in 3+ years I don't think we need to keep it around.
