[PATCH] live-vm-common.bbclass: Allow to use different kernel image than KERNEL_IMAGETYPE for /vmlinuz

[Martin Jansa <martin.jansa@gmail.com>]

* syslinux config hardcodes kernel image as /vmlinuz add warning message
  when the selected image doesn't exist and allow to select different image
  with VM_DEFAULT_KERNEL variable (qemuboot.bbclass is using QB_DEFAULT_KERNEL)
