user - Prevent user fact lookup failure if LOGNAME is set (#17029) (#73439)
The `UserFactCollector` queries the user login name via
`getpass.getuser()` and looks up the corresponding entry
in the password database.
The login name may differ from the actual user name,
eg. if the `LOGNAME` env variable is set. The lookup
fails in this case. Added a fallback in this case that
tries to get the entry via the user ID.
