Update of HLT b-tag validation code in 74X

[silviodonato]

This PR basically sync the 74X HLT b-tag validation code with the 75X version.
The only difference is about the trigger names.
Here the names that are different are:

• HLT_CaloMHTNoPU90_PFMET90_PFMHT90_ID
• HLT_PFMET120_NoiseCleaned_BTag

In this way we get a validation code that is compatible both with the old HLT menu (eg. HLT_CaloMHTNoPU90_PFMET90_PFMHT90_IDLoose_v1) and with the new one (eg. eg. HLT_CaloMHTNoPU90_PFMET90_PFMHT90_IDTight_v1)
