Revert "boot-directdisk.bbclass: use rootfs UUID by default"
This reverts commit
8ca8e2e5bf4a9f01dc48300149a8e1d71d715400.
Further testing showed the kernel does not support root=UUID; it is
something typically handled by the initramfs.
Because boot-directdisk.bbclass cannot know whether it is using a
suitable initramfs, root=UUID cannot be the default. Instead, it will
have to be set in image recipes on a case-by-case basis.
