Fixing AUTOPAUSE on Raspberry Pi 4s (#708)

Browse source 
* Replacing killall with pkill and ps -a to ps -ax

* Adding net-tools and removing -q from pkill

* Missed the resume.sh

* Christ there's a lot of ps calls

* Adding -x to health.sh, replacing killall with pkill in sudoers-mv, and replacing su-exec with gosu in knockd-config.cfg
