[Addon] Add option for booting Garlic OS 2 also from TF 1 near Stock OS

[GeAd23]

If I add some lines in the dmenu.bin file for test if folder /boot2 is exist then set mount point to /boot2 instead TF2 /boot folder.
If I add then a symlink from boot -> boot2 all other scripts must be working without any other changes.
Without the symlink the init script can’t work.
Is this the right hypothesis ?
I don’t have a device here at the moment to test it out. But I can make a pull request with my changes or give you the file for testing.

Yours Sincerely
