[bug#42758] [PATCH] gnu: foo2zjs: Fix install phase.

["Boris A. Dekshteyn" <boris.dekshteyn@gmail.com>]

* gnu/packages/cups.scm (foo2zjs): Fix install phase

Existed package definition builds fine, but de-facto it doesn't work
as expected. This quick and dirty patch make it's functional (tested with
HP LJ M1005, at least i'am able to add printer, configure, and print test
page through cups web interface), but needs some further work (fix and install
udev rules and hotplug helper) to make it fully functional.
