images: Ensure that the manuals from extra-packages are available

Until now, only the packages that are present in the fedora base image,
and had their documentation stripped out, were being tested for the
availability of documentation.  There were no tests for the extra
packages that get added to the base image to form the fedora-toolbox
image.

The util-linux and xz packages were picked as examples for these new
tests.  The xz package is a particularly good example because it has
translations for its manuals.  It can help test that the fedora-toolbox
image is localized just like Fedora Silverblue and Workstation.

Only the images for currently maintained Fedoras (ie., 37, 38 and 39)
were updated.
