Fix segfaults when upower is not running.

On my system, these patches stop xfsettingsd (from XFCE) from crashing
and dumping core during session startup. Thus, it can actually apply the
settings it is supposed to.

I just wish upstream had done a bugfix release, the patches are from 2016 :(

Fixes PR pkg/53455, which I filed :)
