On many servers, the ctime doesn't have sufficient granularity to show
an apparent change between rapid writes, but some are able to do so.
Have the test also check the ctimes here and pass_warn if it doesn't
change after every write.

I've been using this some to test the multigrain ctime patches, and I
think it'd be a reasonable addition. We could also consider adding a
separate test for this.
