Accepting request 901117 from home:dimstar:Factory

- Bump version up to 3.1. The --replace parameter only appeared in
  systemd 238, so we need to ensure to get the update order correct
  for sysuser-generate when using the 3rd command line parameters:
  * systemd -> sysuser-tools -> system-{user|group}-FOO.
- Add Conflicts systemd < 238 to sysuser-shadow
- update sysuser_requires to request sysuser-shadow 3.1
