libxl: advertise system qemu instead of qemu-xen in caps Xen in SLE12 SP2, openSUSE Leap 42.2, and Tumbleweed will no longer provide qemu-xen (aka qemu-upstream). Instead, the qemu binary from the distro qemu package will be used. Change the libvirt capabilities to advertise /usr/bin/qemu-system-x86_64 as the default , instead of the qemu-xen one. See FATE#320638 for details.
