qemu: update Xen packages names for the xen-tools recipe
The Xen recipe has been divided into separate recipes for the hypervisor
and tools in meta-virtualization commit
545461ba, so the package name
references in the qemu recipe need to be updated to the new xen-tools
packages. This change allows the temporary bbappend applied to qemu in
meta-virtualization in that change to be retired.
