test-network: wait for a while if manual policy is always-{up,down}

If wait_operstate() is called super quickly after ip command, then the
up/down state may not be changed and propagated to networkd, and
wait_operstate() mistakenly pass with the previous state.

To avoid such situation, wait for a while to make networkd actually
detect the interface brought up/down.
