gnome-session: source profile for wayland sessions too

By default gnome-session doesn't source this. Since GDM Wayland
isn't launched from a shell it doesn't source profile either and
instead wants us to use /usr/share/gdm/env.d or /etc/enviroment.d
(which is systemd specific). So instead we force gnome-session's
hand to just source /etc/profile.

fixes #8613
