* 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.

Thanks! I satisfied the linter and made the commit message more
descriptive, and pushed as cf066b7a4eb1426b17442e0bcb779e7d7ff4e150.

I hope you will find time for the "further work" :)
