c++: Fix cp_build_function_call_vec [PR 98626]

I misunderstood the cp_build_function_call_vec API, thinking a NULL
vector was an acceptable way of passing no arguments.  You need to
pass a vector of no elements.

PR c++/98626
gcc/cp/
* module.cc (module_add_import_initializers):  Pass a
zero-element argument vector.
