sanity.bbclass: vmdk and live can't be built together

Both vmdk and live use syslinux, but they have different/conflicted
configurations, the main conflictions are:

                    vmdk                live
SYSLINUX_ROOT       root=/dev/sda2      root=/dev/ram0
SYSLINUX_LABELS     boot                boot install
INITRD              No                  yes

So it would make the boot menu strange and vmdk can't be boot, we need
add a few extra vars to fix the problem such as SYSLINUX_ROOT_VMDK
SYSLINUX_ROOT_LIVE, but that needs a lot of changes in the code, so just
add a sanity checking for it.
