fix enforce2d has to be defined after fixes with enforce2d_flag set

Browse Source 
this check currently only applies to rigid fixes and is needed
so that their respective enforce2d function is called _after_
the post force functions. this is required in combination with
commit a9ff593763 to allow rigid
fixes use the langevin option correctly for 2d systems
