Use newlist's automate option

It appears that simply setting stdin to an empty string is
insufficient to make newlist calls from Ansible correctly look like
they're coming from a non-interactive shell. As it turns out, newer
versions of the command include a -a (--automate) option which does
exactly what we want: sends list admin notifications on creation
without prompting for manual confirmation.

Drop the test-time addition of -q to quell listadmin notifications,
as we now block outbound 25/tcp from nodes in our deploy tests. This
has repeatedly exposed a testing gap, where the behavior in
production was broken because of newlist processes hanging awaiting
user input even though we never experienced it in testing due to the
-q addition there.
