fix integer overflow in WIFSTOPPED macro
the result of the 0xffff mask with the exit status could have bit 15 set, in which case multiplying by 0x10001 overflows 32-bit signed int. making the multiply unsigned avoids the overflow. it also changes the sign extension behavior of the subsequent >> operation, but the affected bits are all unwanted anyway and all discarded by the cast to short.
