Subject: xen: use bzImage for boot (instead of vmlinux)

Testing with the latest oe-core was unable to boot and
only syslinux was running.

It appears that the desired kernel is not on the /boot
partition, and hence the system can't continue.

bzImage is installed and available, so we switch to that.

We also ensure that both kernel-vmlinux and kernel-image
are installed to the rootfs so we can have choices in
the future.
