flatpak: fix setting environment variables on gdm
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**

This doesn't affect `GDM -> gnome` due to: https://github.com/void-linux/void-packages/pull/9126
However it does affect `GDM -> <anything other than gnome>`

See: https://wiki.gnome.org/Initiatives/Wayland/SessionStart

(`/etc/profile` never gets loaded in GDM)
