ffi: bugfix: zarray put accessing last element.

A zarray of length N is requiring the Lisp vector to be
of length N.

* ffi.c (ffi_array_put): Reorder logic in the loop so that
when we are putting out the terminating null element of a
zarray, we do not access the corresponding element of the Lisp
vector. Thus if the zarray is N elements wide, the Lisp
vector need only be at least N-1 elements wide, not N.
(ffi_array_in): Copy the null element of a zarray to the
vector only if the vector object at least N elements.
If the vector is nil so that we have to construct one,
construct a vector of N-1 for a zarray.
(ffi_array_get): For a zarray, construct a vector of N-1
elements. Do not even fetch the null.
