Remove all cal_* constants from pr2_description (ros ticket #3773)

the reference should really be '''cal_${side}_wrist_roll_flag''', but xacro does not support nested parameters at this time. Both '''cal_r_wrist_roll_flag''' and '''cal_l_wrist_roll_flag''' in urdf/common.xacro are zeros so I guess it's not a problem for now.

[berger] Given the new calibration system, the entire cal_xxx xacro-based calibration system should probably go away at some point, so I'm not too worried about this particular problem.

[vpradeep] I need to remove all those xacro constants...
