ndb_types.test: sleep a bit longer, to ensure that timestamp > @now

mysql-test/t/ndb_types.test:
  Sleep a bit longer, to ensure that timestamp changes between:
  set @now = now();
  and:
  insert into/update t1
  
  Test case failed (select timestamp>@now from t1 ==> 0, should be 1), and passed when run again.  This should(?) avoid that fluke.
  
  Clean up test file a bit while I'm here.
