Fix xdg-desktop-portal-gtk spam in greeter session

Browse Source 
The greeter's niri session triggered D-Bus activation of
xdg-desktop-portal-gtk, which failed 17x on every boot because
WAYLAND_DISPLAY is not set in the greeter's D-Bus scope.
Setting GTK_USE_PORTAL=0 prevents GTK from requesting portal
services the greeter does not need.
