check-suspend-resume: sleep 1s before rtcwake iteration - #651

After some kernel update, we start to observe a timeout issue on several JF devices. As we are not going to fix the kernel, this workaround is applied. Accroding to the solution in this patch, the device may get into sleep before netcat can send out messages, this maybe related to network issue in the kernel, or network route is too long between JF and SH, etc. In this patch, we add a 1-second sleep to wait a stable connection before running rtcwake.
