Bug#1004943: qemu-guest-agent shutdown now depends on systemd-logind > dbus?

[Michael Tokarev]

It looks like there was a bug in qga which effectively makes it to fail on 
non-systemd
systems:

https://gitlab.com/qemu-project/qemu/-/commit/86dcb6ab9b603450eb6d896cdc95286de2c7d561

It looks it's worth to pick this commit up.

Thanks,
