Update to 20191018.00.
Follow-up to bug 238561, which did not fully fix the port.
Major changes in the package:
- Upstream moved to another github repo
- Upstream versioning numbering changed to dates
The patches that area included were already sent upstream.
The only missing feature is the usage of oslogin in the group database that is
not working (it causes "sudo su" with an oslogin user to stall). But this
wans't present in the last version, so it is left disabled for now until we
have a better solution.
