On fedora 18 the package pyOpenSSL is conflicting with one of the
packages needed to build the bootstack image. The problem gets sorted
if you install pyOpenSSL at the beginning of the image building process
and this is what this patch is doing.

Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.
