  Bugfix: correcting re-scaling of NMSSM u/d-tadpoles to yield singlet tadpole

Thanks to Sebastian Poegel.

The 2-loop singlet tadpole can be obtained from the u/d-tadpoles by a
re-scaling, i.e.

   t_s = (vd/vs) t_d

where t_s is the singlet tadpole and t_d is the d-type tadpole diagram
with mass dimension GeV^3 (i.e. not divided by the VEVs).

The functions tadpole_higgs_2loop_at_as_nmssm() and
tadpole_higgs_2loop_ab_as_nmssm() return the NMSSM tadpoles, divided
by the corresponding VEVs, i.e. they return

   T_d = t_d / vd
   T_u = t_u / vu
   T_s = t_s / vs

Thus, to obtain T_s one has to calculate

   T_s = t_s / vs
  = (vd/vs) t_d / vs
  = (vd/vs)^2 t_d / vd
  = (vd/vs)^2 T_d

Before this commit, the incorrect relation

   T_s = (vd/vs) T_d       (incorrect)

was used.
