If the process does not exist, the error message of `kill` command is a
little bit confusing:
`kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]`
Using `killall` in `/s6/debian-root/etc/services.d/pihole-FTL/finish` to
kill the process, like what we do in `cron/finish` & `lighttpd/finish`,
will make the usage in this project more consistent, and also, the
command `killall` will provide better & friendly output, like:
`pihole-FTL: no process found`

- Add a new container environment variable allowing to specify the user to run the pihole-FTL process as. Defaults to root.
- Set inherited capabilities attributes on the pihole-FTL file to automatically grant runtime permitted capabilities when available in the bounding set. This allows dropping root before starting pihole-FTL without failing with a permission error if the capabilities are not available to the container (the process may still error out if performing an operation requiring the capability).
- Add some information on capabilities to the Readme file.
