Error while mmapping for a binary constants file for zOS.

[christopherlmunoz]

After calling a model that has its constants stored in a binary file on zOS, it may successfully open the file but fails to map it. In this case, the model is ~400MB.

bash-5.2$ client/bin/modelzoo --lib bertsquad-10.so --file bertsquad-10.tests --validate -m VERBOSE --fc-parms 0.01,0.021655,1,10
