Since we are using bash syntax in some of the element fragments,
we should make sure we use bash for all of them, so that things don't
break on systems where /bin/sh != /bin/bash.

devstack-gate needs to be able to make an image that has pre-downloaded
but not installed a sequence of packages. To support that, add a -d flag
to install-packages to allow downloading but not installing. -d passes
through on a dpkg install, and with this patch should be transformed
to --downloadonly which is the yum version.

ARM doesn't have a generic Linux image due to the soc-specific nature of Linux
kernels today, so we drop the manual installation of that package, replacing it
with a dist-upgrade instead. This involved tweaks to the dpkg and fedora
install-package scripts.
