elogind 239.2-1+debian1

[Mark Hindley]

Now elogind has been accepted into Debian, I have a new version for review
before upload.

 * New upstream release v239.2.
 * Support /var/lib/dbus/machine-id as an alternative to /etc/machine-id
 * Enable testsuite
 * Include missing busctl manpage.

For review, it is available at
https://git.devuan.org/LeePen/elogind/tree/debian. 

Ian, I am unsure about your "dversionmangle=s/\+nosubmodule//" in
debian/watch. I think it is broken and should be in a comma separated list with
the filemangle option. I don't use dgit, does it still need to be there?

Thanks

Mark
