Report CPU time spent in child processes of ExternalLHEProducer [9_4]

[Dr15Jones]

When accounting for CPU time used by a cmsRun job, we need to also include the CPU time of the child processes launched by ExternalLHEProducer.

backport #22100

[cmsbuild]

A new Pull Request was created by @Dr15Jones (Chris Jones) for CMSSW_9_4_X.

It involves the following packages:

Comparison job queued.

[perrozzi]

I guess this is needed in 93x (used for GEN-SIM) and not 94x (used for DIGI-RECO) right?

[perrozzi]

sorry to ask again: is this really needed in 94x?

[fabiocos]

@perrozzi This is not strongly needed for 94X, as no massive GEN production is expected here to my knowledge, but it is in production in master since quite sometime, and it doesn't harm either

This pull request is fully signed and it will be integrated in one of the next CMSSW_9_4_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_10_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
