Fixes problems found by set -eu and pipefail, including:
-Many unset variables
-Commands that can fail under normal circumstances, which breaks
with set -e. This change swallows those expected errors to allow
our existing error code to handle them.
-The dkms element was not finding Fedora kernel versions correctly.
This may be an issue for other distros too, but since Fedora was
working fine without this functionality I only changed it to print
a warning message rather than failing the build when it happens.
-The ramdisk init script will not be set -eu because if it fails
the result is a kernel panic, which can be tricky to debug.
However, in testing with set -e a few failing commands were found
and have been fixed in this patch.

Move whether the package or source install type is enabled out of the
source-repositories element and into the base element.
source-repositories wasn't a great fit for this functionality to begin
with.
Specify the install type for an element via the
DIB_INSTALLTYPE_<install_dir_prefix> environment variable.
Additionally with this approach, any new install type can be added
in an element, without having to update source-repositories or anything
in dib.
You could just write your install type implementation under
nova-foo-install, then define DIB_INSTALLTYPE_nova=foo in your
environment, and the scripts under nova-foo-install would get run during
the image build.
Source installs (any scripts under <install_dir_prefix>-source-install)
is the default install type for all elements.

This will write two files in /etc/ that contain the environment and
command line arguments used in the creation of an image. This should
assist with later efforts to repeat the creation of an image.
