Looking for reviews PR 279803 Diff D45618 www/tt-rss simplify rc script

Looking for reviews of the simplification of the ttrssd script from
www/tt-rss.

While looking to add status I realized with daemon the need to
check/wait for a local database could be transitioned in to daemon's -r
-R options retrying the child process on failure and move this to
command and command_args.

The only remaining issue that could occur is when the service needs to
be stopped and doesn't have a child process.  It appears daemon eats the
signal until it's running a child and if the rc needs to handle this.
