py/objstringio: Slightly optimize stringio_copy_on_write for code size.
With the memcpy() call placed last it avoids the effects of registers
clobbering. It's definitely effective in non-inlined functions, but even
here it is still making a small difference. For example, on stm32, this
saves an extra `ldr` instruction to load `o->vstr` after the memcpy()
returns.
