Remove hardcode default values of UCI variables from evaluation

Browse source 
This is the same change we have already done in search.cpp,
this time for evaluation.cpp

If a variable will be populated reading an UCI option
then do not hard code its default values.

This avoids misleadings when reading the sources.

No functional change.
