bootimg.bbclass: fix settings for grub-efi.bbclass

Fixed:
- Found potential conflicted var LABELS ...
  Set LABELS to "boot install" would build out broken images when build
  vm + live together, use set_live_vm_vars() to fix the problem.

- Use ROOT and LABEL in boot-directdisk.bbclass and image-foo.bbclass,
  they are not only used by syslinux.bbclass, but also grub-efi.bbclass,
  add "SYSLINUX_" prefix would mislead users.
