Disabling Upower support in xfce4-settings

[truetechie@tutanota.com]

Hello,

When compiled with --enable-upower-glib, xfce4-power-manager doesn't seem to re-enable laptop displays after suspending the system. And, for that reason, this is disabled by default upstream... but it was explicitly re-enabled in Debian for some reason.  I reported this issue as a critical bug under #991788 in xfce4-settings and was told that xfce4 maintainers in Debian would have to decide whether or not to change this. However, it has been a while and I want to bring attention to it further, especially as an update without attention to this feature has already been pushed to unstable.

Upstream bug report: https://gitlab.xfce.org/xfce/xfce4-settings/-/issues/222

Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=991788

Thank you,

Elliot
