FFI: Hold a weak reference to the CIF made by `procedure->pointer'.

* libguile/foreign.c (scm_procedure_to_pointer): Keep a weak reference
  to CIF so that it is not reclaimed before POINTER.  Before that it
  could be reclaimed and typically reused to store the CIF of another
  procedure with the same arity, leading to obscure wrong-type-arg
  errors.
