Disable system env generator to work around selinux denials

The system env generator is used to get the list of flatpak apps in
gnome-initial-setup for parental controls support. We don't have
parental controls enabled in F33 and F34 (although it's planned for
F35), so we can just disable the system env generator to work around the
selinux denials for now while we don't have the selinux policy side
changes figured out.
