[bug#27344] [PATCH v3 8/8] gnu: Add qucs-s.

[Theodoros Foradis <theodoros@foradis.org>]

Having run "guix lint" before formatting the patches, I split some lines
in two, and that caused some text substitutions to fail in qucs-s
package, which I did not catch in time.

This patch (applied on top of [PATCH v3 8/8] gnu: Add qucs-s.) resolves
the issue. If it is preferred that I send the whole patch again, please
ask.
