ffi: bugfix: null terminated string as flexible member.

* ffi.c (ffi_char_array_get, ffi_zchar_array_get, ffi_wchar_array_get,
ffi_bchar_array_get): Rearrange so that we test for tft->null_term
first, and not nelem == 0. If nelem happens to be zero, but we are
supposed to decode a null-terminated string, we will do the wrong
thing and return the null string.
(ffi_varray_in): The body can't be conditional on vec being non-nil,
because then we do nothing if we don't have a Lisp object, which means
we skip the cases when we should decode a null-terminated array.
Now if vec is nil, we must guard against calling ffi_varray_dynsize.
