config: u-boot: bypass the u-boot script on Traverse Ten64

The Ten64 board runs a U-Boot which works best directly
booting EFI. Attempting to load your own DTB or other steps
will cause issues.
(see https://ten64doc.traverse.com.au/faq/#common-issues)

The current stable Ten64 firmware unfortunately searches for
boot.scr before bootaa64.efi. So redirect it back to the EFI path.

A future Ten64 firmware package will prefer EFI first before
any boot script avoiding this issue. I will provide a patch
reversing this when that day comes.
