The fedora element downloads images too, so we should re-use the caching
code from the ubuntu element.
There doesn't seem to be other examples of code shared between root.d
scripts. In the fedora and dpkg elements we copy install-packages into
the chroot, but that model doesn't apply when we're running scripts
outside of the chroot. Seems sane to just run it directly from the bin/
dir in the temporary hooks directory.

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.
