Hello,

This is a simple fix/workaround for https://issues.guix.gnu.org/50789

As discussed there, there is not a perfect solution for syncthing-gtk writing ~/.config/autostart/Syncthing-GTK.desktop with the Exec line pointing to the store path of ".syncthing-gtk-real". I've opted for a simple fix that won't break upon changes to the syncthing-gtk store path that was done similarly to e.g. the desktop files Flatpak writes in 9c4244cc73db4d5c3adf6f8342f6b08b39dd3628: just use plain "syncthing-gtk". While this means different syncthing-gtk could conflict (whatever is first in PATH wins), that seems unlikely given this package is just a frontend to syncthing. Anyway, seems like the best option right now so that the autostart file is usable and won't break.

Thanks,
John
