[OSSTEST PATCH] TestSupport: use qemu-img to create vhd image

[Wei Liu <wei.liu2@citrix.com>]

We would like to delete blktap2 from xen.git at some point, but vhd-util
is part of blktap2. Let's switch to use qemu-img to create vhd image to
remove the dependency on blktap2 in osstest.

Note that vhd format is named "vpc" in qemu-img.
