Subject: [PATCH] sim: added missing include to mathexpr.hh

mathexpr.hh uses std::function<> but was not including the appropriate
header, which resulted in an error

build/ARM/sim/mathexpr.hh:51:18: error: 'function' in namespace 'std'
does not name a template type
     typedef std::function<double(std::string)> EvalCallback;

This commit adds the missing include.
