If accountsservice is not installed, then LightDM does not hide users created by systemd with DynamicUser=yes in the login screen.

Add /sbin/nologin to hidden-shells in /etc/lightdm/users.conf, systemd uses that for dynamic users.

Additional info:
* package version(s)
systemd 239.0-2
lightdm 1:1.26.0-1
accountsservice *not* installed

Steps to reproduce:
run a systemd service with DynamicUser=yes and switch to the login screen.
(The service must not contain a User= directive that points to an existing user in /etc/passwd)

systemd-run --pty --property=DynamicUser=yes /bin/sh

getent passwd
run-u16702:*:64024:64024:Dynamic User:/:/sbin/nologin

Seems to be covered by optional deps, but we'll see what the maintainer wants to do.
