subprocess.check_output() has been introduced in Python 2.7, so the
script will fail when trying to install stuff in guests with Python 2.6
and older (like RHEL 6 / CentOS 6, for example).
Thus gracefully fallback to subprocess.Popen() when
subprocess.check_output() is not available.

The latest update to package-install captures both stderr and stdout
from pkg-map, unfortunately, pkg-map has a 'missing-ok' option
which causes it to print an error message on stderr.
The result is that package-install tries to look for packages named
"Missing", "package", "name", etc.

Instead of doing the work in the image of parsing through the element's
package-install declarations, we can squash it on hostside, where we
have both YAML and JSON available to us, and then emit a single
pre-processed file into the target to be used later.

We currently support package-installs definitions which has some
limitations and oddities. This new format requires only one definition
which does not reside in our run-parts directories and follows a
consistent naming scheme (package-installs.yaml).
