xen: Account for stolen time

This patch accounts for the time stolen from our VCPUs.  Stolen time is
time where a vcpu is runnable and could be running, but all available
physical CPUs are being used for something else.

This accounting gets run on each timer interrupt, just as a way to get
it run relatively often, and when interesting things are going on.
Stolen time is not really used by much in the kernel; it is reported
in /proc/stats, and that's about it.
