The idea is copied from commit df0b217f3df2c36a32e5c4afaec36a28bfc77bbb:
[ classes/image_vm: allow different filesystems to be used for VM images ]

The same logic should apply to image_live.bbclass, to allow other
filesystems to be used vs just ext4. The default value of ext4 is kept
so there is no functional change unless LIVE_ROOTFS_TYPE is set in the
inherting recipe.

getVar() now defaults to expanding by default, thus remove the True
option from getVar() calls with a regex search and replace.

Search made with the following regex: getVar ?\(( ?[^,()]*), True\)

Changed deployment directory from DEPLOY_DIR_IMAGE to
IMGDEPLOYDIR to make sstate machinery to do final deployment and
generate manifest.

Renamed variable deploy_dir to deploy_dir_image in selftest code
to avoid confusion with DEPLOYDIR variable.

Updated the code of rootfs.py:Rootfs class to use IMGDEPLOYDIR variable
as it's now used as a new deployment destination.

Since mtools has been patched to live with filesystems with sizes
not divisible by sectors-per-track, we no longer need to try to
set the size based on our guess of the sectors-per-track dosfstools is
going to use.

This aligns with image-vm, and makes sense for wic bootimg-efi images, which
don't actually want any of the live installer bits.

When the user only builds iso + efi only, the syslinux-native which
provides isohybrid is required to build iso, so add syslinux-native to
DEPENDS.

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.
