gnu: cups-minimal, cups: Update to 2.4.2.

* gnu/packages/cups.scm (cups-minimal, cups): Update to 2.4.2.
[arguments]: Remove --disable-* #:configure-flags as they do nothing.
Add (different) --without-* ones that do.
Run a newly passing test; skip a newly failing test.
[home-page]: Link to specific subdirectory.
[description]: Better describe the state & direction of the project.
* gnu/services/cups.scm (comma-separated-string-list-or-#f?)
(serialize-comma-separated-string-list-or-#f): New procedures.
(cups-configuration): Update <default-auth-type> and
<browse-dns-sd-sub-types> defaults.
Remove obsolete <classification>, <listen-back-log>, <page-log-format>
and <rip-cache> fields.
Add new <max-subscriptions>, <max-subscriptions-per-job>,
<max-subscriptions-per-printer>, <max-subscriptions-per-user>, and
<ready-paper-sizes> ones.
* doc/guix.texi (Desktop Services): Likewise for their documentation.

-jobs.  It supports printing to both local (parallel, serial, USB) and
-networked printers, and printers can be shared from one computer to another.
-Internally, CUPS uses PostScript Printer Description (@dfn{PPD}) files to
-describe printer capabilities and features, and a wide variety of generic and
-device-specific programs to convert and print many types of files.")
