Bug in check for non-reachable files

ATLMCPROD-10024

grep include mc.Ph_PDF4LHC21_WpH125J_Wincl_MINLO_LHE.py 
include("PowhegControl/PowhegControl_HWj_Common.py")
include("Pythia8_i/Pythia8_A14_NNPDF23LO_EvtGen_Common.py")
include("Pythia8_i/Pythia8_Powheg_Main31.py")
include("Pythia8_SMHiggs125_inc.py")

This appears as a bug because PowhegControl and Pythia8_i are known to Gen_tf but are obviously not present in the DSID directory. To do this properly one would actually need to run Gen_tf (where Gen_tf looks for the jO is based on what is in the cmake file which might change).

So basically all tests should be removed. Perhaps one which can stay is to check if there is any include pointing to afs but this only happened once in 1500 MRs, so I would prefer to completely remove this check.

@mgignac any objection?
