fix '&stg_interp_constr_entry' FFI type to be FunPtr

Summary:
It used to be Ptr, which is slightly incorrect.
ia64 has different representations for those types.

Found when tried to build unregisterised ghc with -flto,
GCC's link-time optimisation which happens to check
data / code declaration inconsistencies.

It our case 'stg_interp_constr_entry' is an RTS function:
   StgFunPtr f (StgFunPtr)
while '"&f" :: Ptr()' produces
   StgWordArray f[];
