DQM/Integration unit tests employing streamer files in input are silently broken

[mmusich]

This issue is linked to #43108

After PR #44892 was merged, all the DQM/Integration unit tests employing streamer files in input are silently broken due to the change of the streamer layout, with errors of the type:

14-Jun-2024 04:54:51 CEST  Can't deserialize registry data (in open file): An exception of category 'FatalRootError' occurred.
   Additional Info:
      [a] Fatal Root Error: @SUB=TBufferFile::ReadClassBuffer
Could not find the StreamerInfo for version 11 of the class edm::SendJobHeader, object skipped at offset 33

This entails the following tests:

• TestDQMOnlineClient-beamhlt_dqm_sourceclient
• TestDQMOnlineClient-beamhlt_dqm_sourceclient-legacy
• TestDQMOnlineClient-ecalgpu_dqm_sourceclient
• TestDQMOnlineClient-hcalgpu_dqm_sourceclient
• TestDQMOnlineClient-pixelgpu_dqm_sourceclient

As reported in #44892 (comment) the reason why the test technically still succeed despite the failures in de-serializing is due to feature of the DQMStreamerReader (see discussion at #43108 (comment)).

A proposed (#44892 (comment)) solution would entail:

• a) reply to the proposal at TestDQMOnlineClient-beamhlt_dqm_sourceclient silently fails in IBs #43108 (comment) to improve the test in order to be able to catch this sort of issue and actually implement the change;
• b) perform the procedure proposed at Handle event meta data changes in streamer files [14_0] #44978 (comment), substitute the current files in cms-data (that have in the meanwhile become broken) with the new format.

Alternatively in #44892 (comment), it was proposed to create new "artificial" streamer file from scratch using the new release, where the files contains known data values and the unit tests show that those values are what is there when read.
