Better kill

[gierig1977]

Original Author of the script from Forum here:

First: For reboot and run on reboots it turned out that a sleep 20 oder sleep 30 do better the job (at least on a UDMSE
that also use Protect ans some other stuff.) Also in the meantime I not kill all DSNMASQ instances, as that will also
kill the AD Blocker ones, I just kill the running main one. That is a bit quicker

kill $(cat /run/dnsmasq.pid)
