jq is used inside xmppc init script but it is not declared as a
dependency. Remove this usage of jq.
jq is a complex piece of software that requires security maintenance and
adds bloat to the image. Using existing tools like jshn and jsonfilter
is preferred where the additional functionality provided by jq is not
required.

service_stop is a legacy function and it should never be used with
procd services which are automatically stopped by /etc/rc.common
Also remove unnecessary boot() which just runs the "start" function.
