Fedora's partprobe does not create devices the same way it does on
Ubuntu. Instead of using partprobe, this patch uses kpartx, which
works on both Fedora and Ubuntu.

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.

This switches $CLOUD_IMAGES and $RELEASE to the DIB_ namespace so
they will survive future changes to the sanitisation of the build
environment.
