Modify DQMGUI upload test to only run in automated environments

I.e., when the cmsbot is running the test for PRs or IBs,
where `CMSBOT_CI_TESTS` is set.

- Also fix the timestamp of the renamed file to include the hour,
which was missing before, it will help with debugging.
- Added a `--help` argument, just in case.
