Instead of running a long command line in the runroot (or locally), move
all that work into a separate script that will be installed. This means
chroot will need to install pungi.
Everything should work as it did before. The only exception to this is
that there is logic to find lorax templates instead of harcoding the
location. This is done using a separate script.
