turris1x-support: fix boot.scr location

The file boot.scr should be in boot folder and not in root,
because then it is not in the same way as it is done for Turris Omnia
and Turris MOX. I checked it with Turris OS 3.x release also, when
boot.scr was introduced for Turris 1.x routers and there is also in boot
folder.

Fixes the following output:
cmp: /boot/boot.scr: No such file or directory
cp: can't stat '/boot/boot.scr': No such file or directory

Fixes: 03c8a7c7 ("turris1x-btrfs: deploy
boot.scr and link the appropriate dtb name")
