Remove --harvesting AtJobEnd option in GEN Relval workflows

[SanghyunKo]

In recent 10_4_0_pre2 release validation campaign, DQMIO files of ALL GEN Relval samples were not uploaded to DQM server due to the wrong run number (999999). This was caused by PR #24920 , the dummy run number parameter of all GEN workflows was affected by the change introduced in DQMSaverAtJobEnd_cff.py because all GEN Relval workflows were using '--harvesting AtJobEnd' option. Since there is no point of using '--harvesting AtJobEnd' option (there is only single harvesting job like any other Relval workflows), simply removing this option can fix the issue.

Fix the issue #25272 . See JIRA ticket 4020 for detailed discussions.

@zhenhu I understand that there is no foreseen drawback by this fix, and it is not even clear from the discussion why this option was used in first place

@kpedro88 this is not upgrade specific, anyway please check and sign it
