ffi: fix carray multiplication overflow checks.
* ffi.c (carray_dup): Do size multiplication using unsigned
type, then coerce back to signed. Check for overflow correctly
by first testing result for negative, then doing division check.
(carray_replace): Add check for negative size, which confirms
overflow.
