Pull up following revision(s) (requested by jld in ticket #1506):
        sys/arch/xen/xen/clock.c: revision 1.26 via patch
Fix accidentally unsigned comparison, which was causing the timer event
handler to run ~forever in the face of slightly unexpected input from
Xen (system_time apparently going backwards).  Pointed out by kardel@.
