Linux.Sys.LastUserLogin probably needs to also cater for wtmpdb

[predictiple]

wtmpdb is a newer sqlite-based logging database to mitigate impact of the Y2038 problem that affects the older logging formats. More distros may migrate to it in future.

With the last updates openSUSE MicroOS and Tumbleweed don’t use /run/utmp, /var/log/wtmp and /var/log/lastlog anymore. This files will no longer be created. /run/utmp will vanish with the next reboot, /var/log/wtmp and /var/log/lastlog will not be created with a fresh installation. On existing systems, the files will stay, but we will not read it anymore. It can be safely moved away by the administrator.
