buf: bugfix: int-buf, uint-buf refer to alloc size.
* buf.c (int_buf, uint_buf): Refer to the buffer length b->len
rather than the underlying allocation size b->size.
Referring to b->size will not only produce the wrong value
when it is larger than len, but b->size can be null for a
borrowed buffer, producing a crash.
* tests/012/buf.tl: Tests.
