xen-image-minimal: enable runqemu for x86-64

Booting this Xen image with QEMU works when launching from the
wic-generated pcbios disk image with the directdisk-xen.wks kickstart
file, so add the variable settings to make doing it simple -- eg:

    runqemu xen-image-minimal nographic slirp

Tested with MACHINEs: qemux86-64 and genericx86-64

Memory allocated to qemu is increased slightly over the default to allow
for running Xen and the Linux dom0 and guest VMs.
