sysntpd server becomes unavailable if the index of the bound
interface changes. So let's add an interface trigger to reload sysntpd.
This patch also adds the ability for the sysntpd script to handle
uci interface name from configuration.
Fixes: 4da60500ebd2 ("busybox: sysntpd: option to bind server to iface")
