Following the new IOzone postprocessing changes, add a new
KVM subtest iozone_windows, which takes advantage of the
fact that there's a windows build for the test, so we can
ship it on winutils.iso and run it, providing this way
the ability to track IO performance for windows guests also.
The new test imports the postprocessing library directly
from iozone, so it can postprocess the results right after
the benchmark is finished on the windows guest.
I'll update winutils.iso on the download page soon.
