Replace MOD_NAME with mod_name in rsrc and feas

Problem: MOD_NAME does not properly set the mod_name var
in the body of the s-f-resource module during t4010 within
the alpine - test-install docker-run-checks CI action.

Solution: Replace the MOD_NAME macro directly with the
mod_name variable in resource.cpp and feasibility.cpp
