[PATCH] tools/kvm_stat: Add Python 3 support to kvm_stat

[Jeremy Cline]

Make kvm_stat support Python 3 by changing the use of "print" to a
function rather than a statement and switching from "iteritems" (removed
in Python 3) to "items".

With this change, kvm_stat is usable with Python 2.6 and greater.
