endSessionDialog: Switch from PackageKit offline updates API to gnome-software
Let the endSessionDialog depend on gnome-software when deciding whether
any offline updates are scheduled and what to after applying them,
instead of using PackageKit, which is not included in distributions
using rpm-ostree and similar.
Another advantage is rather than implementing similar calls for various
package managers and systems in gnome-shell, these implementations should
go into the gnome-software, which should know about them already.
