Remove hand-rolled abs functions from games/trackballs

During the exp-run in bug 208158, it was found that games/trackballs gives errors with libc++ 3.8.0 [1]:

glHelp.cc:132:13: error: 'abs' is missing exception specification 'throw()'
inline Real abs(Real v) {return v>0.0?v:-v;}
            ^

This is because the program is attempting to define its own version of abs(), which conflicts with the one from <cmath>.  Fix it by removing the custom versions of abs().
