base-files: add wrapper for procd service list command

A service managed by procd does have a json object with usefull information.
This information could by dumped with the following command.

ubus call service list "{ 'verbose':true, 'name': '<service-name>)'". }"

This line is long and complicated to enter. This commit adds a wrapper
call to the procd service section tool to simplify the input and get the
output faster.

We could now enter the command /etc/initd/<service> info to get the info
faster.
